I figure morality as a topic is popular enough and important enough and related-to-rationality enough to deserve its own thread.
Questions, comments, rants, links, whatever are all welcome. If you're like me you've probably been aching to share your ten paragraph take on meta-ethics or whatever for about three uncountable eons now. Here's your chance.
I recommend reading Wikipedia's article on meta-ethics before jumping into the fray, if only to get familiar with the standard terminology. The standard terminology is often abused. This makes some people sad. Please don't make those people sad.
So, let's assume your definitions, and also assume a Person X.

But I hate Person X. Which makes me the evil one.

You're confusing a few different issues here.
So your utility decreases when theirs increases. Say that your love or hate for the adult is L1, and your love or hate for the kid is L2. Utility change for each as a result of the adult hitting the kid is U1 for him and U2 for the kid.
If your utility decreases when he hits the kid, then all we've established is that -L2U2 > L1U1. You may love them both equally, but think that hitting the kid messes him up more than it makes the adult happy, you'd still be unhappy when the guy hits a kid. But we haven't estab... (read more)
