What if I told you that I'm something of a sociopath?
Why do you feel like you're a sociopath?
Some of my friends also think so.
A lack of empathy for others is not good. If you feel you lack empathy and compassion, you should talk with a therapist. They can help you develop those skills so you don't harm others.
I haven't hurt anyone. I've robbed, but that's just because they have money.
Well it sounds like you could be in a bit of a rut mentally. I strongly suggest you seek out a medical professional to help you with your mental health.
