I believe discussion on this flares up now and then because it is an easy answer, tough decision.
If you make this decision for others: of course this is the most ethical thing to do, the data isn't ambiguous.
If you are yourself affected: Oof. Yes it might be better for society, but personally I value this and that, and I am but one and would rather wait on legislation before I do anything.
We love to argue it because one side thinks experiencing it taints your view, the other that only reading data misses the point. Can be about indoor cats, vegan diets or pineapple on pizza, the argument itself never matters.
