"I don't think you get what we're saying. Shay clearly detests the unnecessary slaughter of innocents, which is partially why he leaves the Assassins."

I clearly understand what you're saying : "Shay says he hate killing innocents so why making him killing innocents in the game". What I say is that it's not the slaughter of innocents Shay detest, but the unnecessary slaughter of innocents caused by following the Assassin's creed, in which he didn't believe anymore. This is why he try to leave the brotherhood, because of his doubts about the creed. He is not like Liam, Achilles, Hope, ect... who see the tragical event as a mean to an end.

If you did something truly bad, like killing someone, you can convince yourself that you did it for a greater good, if not and if you're not a sociopath, you will feel overwhelming guilt. This is why I said in my previous messages that I understand that someone can be ready to commit certain acts for a cause he believe in, than for another in which he no longer believe.

And also, the game span a decade, people change or at least evolve during that kind of time ...
