God, they can't be that bad! Well, actually they can, I've seen lots of evil people... And no, you're not one of them, you're a lovely person, if you weren't, you wouldn't have me, or any friends, or family that loved you. :p
What makes you think of yourself as that much of a bad person, I know how you can be, short tempered and perhaps doesn't care about other peoples feelings at the time, but in a way, all of us are like that, careless and unforgiving.
Listen, love. Many of us think that life is this sort of line, or goal, that we have to cross over, and those who cross over it are the ones that are 'succesful' or 'happy', and some people who like to bring others down will rub that line out and draw it much farther away and harder to reach, and those who do cross it are 'popular' 'rich' or simply, 'in' But life isn't made to be like that, the only line that you have to cross, is the one that you make, and set for yourself, almost like a trail of footprints in a line, leading towards whatever it is you want. And that's the most important thing, so you're right, stop pitying yourself and go smile at the world and grab a hot dog. :p
