WANTING TO DESTROY SOMETHING DOES NOT MEAN EVIL. I WANT TO DESTROY A LOT OF THINGS, BUT I'M NOT EVIL.
Sending Karl to New York to FEED HIMSELF. Karl was hungry, he tried to drink Ella's blood, Sofia and Ethan attacked him, he retaliated. SELF DEFENSE.
Jin was merely conducting a la John Mote, and magically the village burst into an enormous swirling vortex of fire. Jin felt that the Confederacy was responsible for this destruction, and so he told Safiria to take her anger out on them rather than him. Her son was mortally injured in the fire, so Jin brought him back to life the only way he knew how.
Kidnapping Ella as collateral for Sofia breaking a prior agreement. JIN WAS DEFENDING THE SACREDNESS OF BINDING CONTRACTS.
Killing Ella for the same reason.
Killing Vi'ir, who attacked him first.
Summoing Umbraceon to destroy everyone who attacked him first.
COLLECTING SOULS OF BANDITS AND OTHER PEOPLE WHO TRIED TO KILL HIM FIRST.
Killing Safiria, who attacked him first and abandoning his TRAITOROUS teammates away. When Benedict Arnold betrayed America, WE DIDN'T JUST LET HIM STICK AROUND. GEORGE WASHINGTON CHASED HIS PANSY ASS DOWN UNTIL THE TRAITOR FLED TO LONDON. The fact that Jin didn't kill them then and there says quite a lot.
Continuing to THINK ABOUT DESTROYING MUNDUS VERITAS.
AH, I SEE ALL THE SELF DEFENSE!!!
