Through his entire journey, Sorey manages not to take the life of another person (human or seraph) with only three very specific exceptions, all towards the end of his journey. Sorey was adamant through the vast majority of the game that the only way to help hellions (and people) was to purify them and help them through their problems. It's a noble pursuit and falls in line with his pure and kind heart, but he started running into snags in this ideology when he had to come to terms with the fact that not only is he the only person capable of purification at that point in time, but that some beings either couldn't be purified, or didn't even want to be. He was then faced with the choice of whether or not to leave them as they were, or kill them. The greater good was supposed to come before his own personal ideals.

In the end, he came to the conclusion that if the only way to 'save' someone was to end their life, then he would be willing to do so. It meant forcing his own judgment and ideology onto the person or being he was 'saving,' but with his limited human lifespan and their limited resources, it was the best solution he could come up with. To this end, he and his friends killed the big brother of one of the party members to save him from a lifetime of suffering as a dragon/hellion, he and his childhood friend/soulmate Mikleo mercy-killed their grandfather when he was abducted and used by the enemy, and then Sorey by himself killed the man who was at the heart of all the tragedy of their current age.

Hands down, the most important relationship in Sorey's life is his friendship/kindship/soulmate-ship/whatever-ship with Mikleo. They were raised together, two members of very different species; Sorey a human, Mikleo a seraph. Seraphim generally don't 'grow up' like humans do, but Mikleo's circumstances were unique, and he instinctually mimicked Sorey's growing patterns as closely as a seraph could. As the only two children in a village of immortal beings, the two were raised side-by-side and became inseparable to the point of seeming like two halves of the same whole to many other characters in the game. Mikleo is the person who knows Sorey the best in the entire world; they communicate without speaking, they know what the other is thinking, and they trust each other implicitly. Mikleo is the only person with whom Sorey allows himself to be a little weak, a little bratty or selfish or childish. Mikleo is the person Sorey goes to first for comfort. They have their own insecurities regarding their different species, but it's never grown to the point where their mutual affection fades. If Sorey was reincarnated as a seraph with no memories of his past life, it is absolutely one thousand percent certain that even if he didn't remember him, he would still love Mikleo with every inch of his soul.

As mentioned in the first question, Sorey is very staunchly anti-murder (and violence in general), though he doesn't shy from it. The epitome of kind-hearted and caring, Sorey would rather resolve issues with negotiation and mutual understanding, though he will put evil-doers to the (non-lethal) sword if they insist upon preying on the weak or perpetuating evil acts. Sorey isn't particularly meek or timid; he's in fact pretty damn stubborn, to the point of becoming a headache for the rest of the party when the easier path would be to avoid confrontation or to take care of things more discreetly. Sorey believes in giving people the chance to do better, believes that just about everybody in the world wants to live their lives peacefully and only need the means to do so, and will give just about anybody second or third chances to mend their ways, especially if he's the one who's been wronged.

While he's had to revise some of his moral code to be a little less of a pushover, Sorey still despises taking lives if it at all can be avoided. So long as he's the only one getting hurt, he'll try appealing to a person's conscience a thousand times before giving up. If he's not the only one at risk though, all bets are off.

Sorey will forgive anyone if he believes the apology and willingness to change is genuine. He's the type to even go against his instincts in an effort to give someone a second chance. Because of the way he was raised, surrounded by love and adoration and encouraged to be honest and true to himself, Sorey has difficulty understanding why someone would ever lie to ask for forgiveness. He's not as naive as he once was, but the habit to trust is a difficult one to break, and one he doesn't want to besides.

Trying to determine the circumstances under which Sorey wouldn't be willing to forgive someone honestly asking for it is extremely difficult. It would change his character fundamentally, and likely not in a good way. If someone was cruel to the point of tormenting Sorey's friends and family for years and years, of their own volition because they enjoyed being cruel, maybe then Sorey would be unwilling to offer forgiveness (though he'd manage a cease-fire, mutual avoidance situation). His own Squire is the leader of an assassin's guild who had a contract out on his life, after all, and one who holds that she'll put a knife in his throat if he looks like he's going to make this Shepherd thing turn into a net loss for humanity. If he can forgive her to the point of calling her one of his closest human friends, then the threshold is pretty damn high.

One of the key sticking points of the game is sacrifice, the manner in which it can and should be offered, and what it means to individual characters. As the Shepherd, Sorey chose to sacrifice a normal life of his own selfish pursuits in favor of dedicating himself to the purification of the world. While he could have given up on his journey of purification, as he journeyed Sorey came to the realization that his world was in much rougher shape than he thought, and that to abandon his journey would mean leaving the world and its inhabitants (both seraphim and humans) in grave danger. Sorey is the type of person who is unable to ignore people in need so, for better or worse, he committed himself to his new cause alongside his companions.

While Sorey hardly hesitates to put himself in harm's way and sacrifice his own health and happiness, up to his own life, he's very reluctant to sacrifice anything of anyone else's. He's struggled in the past with the difference between trying to protect those he cares about and denying them their own right to decide what they want to sacrifice. His noble heart can sometimes manifest as being controlling, preferring to take a full burden onto himself rather than allow even his friends and family to help shoulder it with him. At the end Sorey was able to respect the wishes of his companions and allow them their own sacrifices, before executing his own final sacrifice of his ideals, his future, and potentially his life. While none of these sacrifices were to better himself and reach his potential, becoming a strong and true Shepherd is almost one in the same for him now due to the extreme ego-death necessary to fulfill a greater duty.
