I believe there was only ever ONE perfectly good person who lived on this earth. His name is Jesus. I say IS because He is still alive in Heaven now.
There are a lot of folks who do good things and there are a lot of folks who don't.
Myself, I try to do good things, but I have made mistakes, I have done wrong in my life. I have also done a lot of good things. I think I am just a regular person. I am human.
That is not to say that you are a bad person either. Since you feel you are a good person, you should try to continue to be one. I will try too! I think we all should do the best at it that we can. Life is tough though, and sometimes you run into someone that just makes your blood boil!!! LOL... I laugh now, because I am over it. But when it was happening, ooooh! Was I mad!!! I think anger has its place, though, really. Sometimes you just have to tell someone off! I did once not that long ago. The person is still abrasive, but is more behind the scenes and discreet about it than before. I figure I accomplished something for all of us who have to deal with that person.
Life goes on. I don't even think that person is bad. I just think that person was annoying. Some people are.
On the other hand, I have met some really nice people too. Ones that most folks would consider to be "good people." I like being around those types of folks. They make me feel good and cared about and loved. They are kind and gentle and they treat me with respect. If I were to call anyone "good" it would be this type of person.
