EVERY THING IS EITHER GOOD OR BAD

There is good and there is bad but if you do bad things does it really mean you're a bad person? Sure you did wrong, but you still could be a good person. Right? Just like if you do good things it doesn't mean you're a good person. How come it doesn't work the same way? if you do bad thigns or even one bad thing your scarred for life as a bad person, but if you do good things or even 1 good thing  you're not branded a good person.who are we to even describe some one as good or bad. Why are we more superior then they are. also if you get bad news it's easier to believe then good news is. Why does everyone look for the bad in peop? Is it to make us feel better about ourselves? there are things in the world that are good, but Everyone always focusses on the bad. bad news always is more important then good. Why can't  everyone except everybody? Even if they are yourt best friends you always notice and look for the bad. Actually, isn't that how we pick our friends. On a good or bad basis. Depending on what kind of person we are, but half of the time it turns out we have a hidden secret (Usually he secret is bad) that makes us not want tobe friends anymore with that particular person. No one is perfect everyone does bad thins, but have you ever noticed if your a good person that usually does good things when you do something bad its worse then if your a bad person who usually does bad things and you do something bad its like nothing and vise versa. To me it's just strange how our whole world is based on good and bad.
