Then Shazuko is Neutral, at best. If he lacks the willingness to sacrifice his own happiness, safety, or even his life, to save or help the innocent, but he also feels remorse for the Evil actions he was forced to perform (yes, they are Evil, even if you felt you were forced to choose the option, because losing your life for making another choice is still a choice), this is a perfect example of a Neutral character on the Good/Evil axis. Even the Evil people can feel generosity towards others and help them if there is no risk to themselves. Even the Evil people can love someone strongly. But it all comes down to how far you are willing to go, to save yourself or someone else.
Shazuko is an interesting character. He is complicated, conflicted, but he knows himself even if he hates what he knows. I hope you have fun exploring his path.
