Bad person according to whom, though? What makes eating meat wrong? That some people decide it is? There's no consensus or laws that make it so, unlike the case with eating humans. You decided you didn't want to be miserable, but I guess you feel guilty because you decided it was wrong? I've decided it's not wrong, and I don't see that anyone can make me think otherwise.
It’s always been bad to us living today, but it hasn’t always been bad to people in the past. I’m not a moral realist because I don’t see what sort of objective facts are moral. The universe doesn’t care. It’s humans who are moral, and what’s considered good or bad varies quite a lot. No, I wouldn’t want to be enslaved, and the golden rule seems like a good principle to live by, but nothing in nature makes it true. It’s a value judgement we moderns make.
