Does your own pleasure justify harm against others?

I have (genuinely) tried really hard over the years to try and see it that way. To try to feel bad about the idea that an animal died so that I could eat it.

It has never worked, not even a little bit. I've been on a farm a few times and have seen my food killed right in front of me, yet it never bothered me neither as a child nor an adult. The most I can do is pretend to care so that other people think I'm a saint, but I genuinely am not capable of feeling anything for the animals that I'm eating. I wonder if that's a biological thing? Like some people are born without the genes that make you sad about this type of thing.

Idk, but in any case, appeals to emotion have never worked on me, and will never work on me. I know there are logical, non-emotional reasons to avoid eating animals, but when I see vegan discussions online focusing on the emotional side of it, I just eye roll and leave. I guess it's ironic, but a lot of vegans I've met IRL and online are lacking empathy.
