I don't know what guilt and remorse feels like, is this normal?

Over the years, I had to teach myself not to hurt other people's feelings. I had to tell myself not to do it because then I'll get caught, lose friendships and have a bad reputation but not really out of guilt. It's basically me just following the rules, imitating known speeches and trying to live a normal life.

However, I have no idea what it really feels to have guilt and/or remorse. They are like complicated concepts to me. Is this normal? To never know what that feels like?

For example, if I were stepping on someone's toes, make someone cry and still nothing registers in my mind. I feel nothing but indifference at the whole situation. I still won't understand why I'm suppose to feel bad.
There are days where I wish I knew how those feelings feel like.
