What do you mean, in many places around the world we kill people society or state considers assholes, including US.

Then we can discuss where is the cutoff line for enough assholishness to go for a slaughter and where something less severe, but practice is here and not going anywhere.

Not really the same as systematically bringing into existence a species with behaviors you find objectionable, keeping them in your proximity so you can experience said behaviors, and then slaughtering them with the excuse that they are all assholes is it?

When you say that roosters cross this line do you mean with respect to their behavior towards you? I'm guessing this can't be that bad since you're much more powerful than they?

Or do you mean towards other chickens? If so, and if it's really that bad, then surely the best thing is to just not bring them into existence in the first place (not systematically breeding them with the intent of slaughtering them)?
