I prefer to see him killed by my father rather than in a slaughterhouse where animals (and people who work there too) are really mistreated.
I’m not a vegan at all but I think we can reduce our meat consumption for instance which could mean less meat but better one with animals better treated in my opinion.
One day, we (humans) will probably all pay for our excess and all bad things we did towards animals and nature in general.
Best wishes
