I hadn't assumed that. First off, few people enjoy that. Second, you don't seem to enjoy going out of your way to hurt people. You just aren't willing to take any effort to avoid hurting people when you know your actions are doing so, unless you care about the people in question. You're simply content to hurt people if you're not emotionally invested in them.

It's the difference between someone who will swerve to hit someone with their car and someone would never do that, but wouldn't swerve to avoid hitting someone if they didn't care about the person in question - except in a much more indirect way and probably on a much smaller scale.

I really doubt you ever go out of your way to deliberately harm people who have done nothing.
