If you were threatened by a non-vegan roommate that they will eat three times as much meat as they used to if you donʼt start eating some meat, would you do it?

What would be more important to you? Not having any blood on your own hands, or reducing the total meat consumption in the household (1 unit from them and 1 unit from you instead of 3 units from them, all per day/week/anything)?

Assuming you have seen your roommateʼs meat consumption and that they would actually start eating 3 times more meat than before, which you would also see.
