nobody has ever had a runt in the litter before?
never drowned a sick animal?
never buried something in your backyard?
death is death, and a smack on the head is just as quick as a needle
kid isnt a fucking serial killer, he had a shitting pissing dog living in his home that was someone elses and it was dying in front of him while the owner didnt do shit but wait for their paycheck to clear

off the fucking dog already, dont wait for your check to do it

if you have a moral objection it should be to the owner who didnt take him in when he decided it needed to be done, damn the monetary consequences right? debt is nothing compared to your pets well being, do whats right! right?

just like the kid who offed the dog did, took care of business, with the dogs best interest in mind, and immediately, no suffering, no $$ in debt, no waiting

either apply your moral high ground to all involved, or keep your opinions on how others should value life/death to yourself

the situation is messed up and the communication between owner and other guy is an issue, but the death of the dog is not the issue imo
