Killing an animal for trophy use or because they might hurt someone is not OK.
How about culling to improve the health and prospects of the herd ? OK, the side effect may be it makes life easier for humans too, but that's not it's main driver.
Deer in the UK are a fucking menace for all sorts of reason. And deer herds benefit from culling (even in Richmond Park). Should I not enjoy venison ?
That said, senseless killing, just for trophies - not even food - isn't great, and I would judge.
