Putting yourself and your own concerns first, to the disregard of the suffering of innocents or the well being of others around you is the type of personal selfishness that typifies classical neutral evil. Shadowheart is classical neutral evil (though with strong signs that she would be otherwise underneath if she were her original self without the brainwashing, and that's showing through more and more with the changes they've made to her), for example.
In the real world, if someone would get beaten up by 5+ guys, you would run away and call the police. You would not step up and try to take out the Goblin leader because you are a "warrior"
Halsin at least is fighting alongside you, so he earns his right to demand that you help him back. The Tieflings just expect to be saved by someone else. And this behavior is what I would call 'egoistical' or even 'evil' - they expect others to risk their lives for them without doing their part.
What I agree with is that my original phrasing "not care" was maybe too harsh. Yes, I do 'care' about the Tieflings plight, but not as much as to risk my life for them. I might sympathize with them or send word to the guards in Waukeen's rest, but I won't take down the Goblin leader without any backup.
