One word : Different.

Everyone is different, different in every way.
I still believe in every human, there's a good side in them.
No one is 100% evil and bad.
No matter how terrible the person is, there's a good part i'm sure.
To me, i really think everyone is unique in their own ways.
There's no perfect person. That i'm sure.

We should accept everyone for who they are, we always do and say stuff without thinking.
We do silly stuff and say nonsense. We just really judge someone way to fast.

Try not to regret if possible, the feeling really sucks when you regret something.

p.s. we know it's wrong to judge people, but we always judge without knowing.
