I need to see more of Wyll, but right now I would peg him as chaotic neutral - maybe with hints of neutral evil.
He paints himself as a good guy, but he clearly isn't. I don't think he really cares about others - all seems to revolve around his personal revenge and family issues. I could easily see him finding an excuse to do some horrific stuff, if it suits him.
While i can certainly see your point of view, I think maybe you are judging Wyll at his worst and only at his worst. In the absence of Goblins, he's a pretty upstanding guy. He likes it when you help the Tiefling compose a song to honor her dead friend, he likes it when you prevent Shadow-Druids from taking over the grove, he likes it when you spare the tiefling child-thief. He likes it when you purify the corrupted hyenas and put them out of their misery. He dislikes being needlessly cruel except with Goblins. Yes, he has a blind spot for goblins, and that does ding him on the alignment chart, no doubt. But to say that he doesn't care about others? That's going a bit far IMHO.
