Honestly, Arne, I wouldn't call "don't care about the tieflings, don't mind what Khaga is doing, and focusing solely on getting a cure for yourself" to be neutral... It's pure self-focused, selfish behaviour to the complete disregard of the suffering of those around you or the cruelties of others. In other words, it's the classical definition of an evil character.
If you had a tadpole in your head in the real world, you would surely not risk your life(!) to resolve problems of Tieflings in a Druid grove fighting against Goblins

But of course this is not the real world but a fantasy story, so I understand that you take an ethical viewpoint that is not really realistic. The problem is that Dungeons and Dragons always defined good as stupid good and evil as stupid evil.
