In your example the “bad weather” means “bad for me/us” (a farmer would probably disagree, for example, as would some animals). Indeed morality is about what’s “bad to others” or to everyone. But since OP didn’t specify to whom, I considered it meant “bad in general”, for the one eating and for the others.
OP included “Ethical reason for consuming animals” in the accepted answer, so answering about morality doesn’t seem wrong.
