There is probably cases where you could try to morally justify anything (like in a survival situation I guess?) but I personally would try to abstain from killing under any circumstance.
The morals around eating animals are luckily not that vague. You do not need animal products to live (say all major dietician organizations) so the only reasons people are eating meat is out of habit or for taste. And pleasure does not justify killing a sentient being.
