My emotions and instincts can be assholes, but I choose to be a good person. So the answer really depends on how much you weigh my instantaneous reaction to an emotional situation vs after my rational brain kicks in and I remember that everything that angers or disappoints me wasn't done for the sole purpose of ruining my day. Oh and little stuff pisses me off way more than big stuff.
I wish I was a better person, but I think I'm alright most of the time.
