Ordinarily I'd feel bad about the situation because obviously we all know how crushing it is/would be to us to lose a parent, but at the same time I know personally if I, for example, knocked up some dumb barely legal girl well over a decade my junior who trusted me, proceeded to try to coerce her into an exploitative sexual relationship with some mentally compromised deviant who couldn't be trusted around children, then essentially abandoned her and my unborn child to bang said mentally compromised deviant, I'd be so ashamed and disgusted with myself I wouldn't even be able to sleep at night or look in a mirror, no matter how much whiskey I drank.
Asking one's self how a normal person would feel if their mother died and assuming that's how it is for Ralph would be kind of like when vegetarians ask "How would you feel if that was you?!" in relation to slaughtering animals...I'm sure it would suck, but so would standing around in a field all day doing absolutely nothing but eating grass and shitting all over myself, or eating my own children, or chasing around the other occupants of my enclosure trying to peck them to death because they have a spot of blood on them. Their ideal existence would already seem hellish to a human.
My point is when you're dealing with animals that know nothing but consuming, rutting, and fighting you can't expect logic or empathy to translate on a 1 to 1 basis, so I honestly can't even tell if I should feel pity.
