I think I am a psychopath
What makes you feel that way?
Because I'm like this guy who always says he wants to kill people.
While it is good to acknowledge the faults you know that you have, you should always want to change and become better. If you think you have a psychological disorder, it would be good to see a psychiatrist to get treatment.
I am just saying what I'm thinking. Other people don't know the way other people think and it is better that way.
The truth about this is going to come out eventually though. If you think that something might be wrong with you, it is always a good idea to talk to someone who can help.
