There's a psychological barrier to ridding yourself of those feelings of guilt and remorse though. Like I said, people who show no capacity for guilt or remorse are called sociopaths. You're born with sociopathic tendencies, you don't condition yourself to be that way.

>does it not follow that you should try to rid yourself of the feelings of guilt and remorse, as they make you unhappy?

For those of us who are not sociopaths, it is far easier to avoid feelings of guilt by conforming to our moral inhibitions, rather than undertake the incredibly difficult, perhaps even impossible task of reconditioning ourselves to no longer feel guilt.
