Well, welcome to the Escapist. Yah you, hope you get used to the site, and enjoy its content.
As for the morality thing, most of the time, the evil-option is completely irrational, and stupid. So, I try to do the things that fit me. Ie, I'll save a little girl's cat out of a tree, and help the small boy get his money from the bullies, but not a middle-aged prostitute man rake in more customers.
In other words, I try to be as nice as possible in games without my character seeming creepy and scaring off all the quest-givers. Being comically evil has always made me feel bitter towards my characters. I played a good-character and bad-character in New Vegas. Some of the Evil dialouge options were rather silly, and how the tribes simply forgive you after the kill 1/3 of their members, piss on their corpses then teabag just seems silly.
And I honestly dislike it whenever morality choices or paths are labeled "Good" or "Bad" or "Kinda Goodie" or "Dispicable Innocent Child", or shit like that. No good or evil, or Renegade of Paragon. 'Cause, really, you shouldn't know anyone who's a massive angel or a gargantuan dickhead. That's just immersion-breaking for me.
