I think it has more to do with simply that the animal was killed in a manner that was intentionally cruel and for pleasure. I think it is partly that the animal is an innocent and was preyed upon by a cruel entity with an obviously twisted psyche looking for an outlet. Compound this with an image of the animal, that, through no fault of it's own is now forced to slowly die with no way to aid itself and no way to communicate it's plight......Fvkkin' awful is what.
The abortion issue is something else altogether in my mind. Many people in many situations with many justifications for their actions. I'd wager that these actions haunt a good many of these people forever, especially if they subsequently have children after the fact. The love for the children that they have must accentuate the sorrow in the actions they took in aborting a child, a sibling, previously. Hard to judge someone. I agree on the whole that it is wrong but it is a huge issue and I don't think the cause behind someone making such a decision is evil necessarily....not in intent anyway. Maybe evil as a premise, in the taking of a life, but I don't for one minute suspect that anyone making such a decision does so out of any twisted sense of pleasure.
I think it's a little presumptuous to assume a person would have no problem terminating a pregnancy. Perhaps in some cases but not as a blanket statement.
Apples and oranges.
