This Anon's a bit kind.He tried to kill the two Yukkuri so their suffering would come to an end.
Killing them instead of trying to take them in. Very kind indeed. Though, they could be shitheads simply crying for their dead parents.
squishing woulda been kinder in my opinion. Would kill them almost instantly, so there's little to no pain.
Then again, these are yukkuri so I shouldn't expect anon's to show kindness to them, even in euthanizing them.
Euthanize means to cause something/someone to die in a way that is considered painless to end suffering.
Make a yukkuri a fire, and he will be warm for a day. Set a yukkuri on fire, and he will be warm for the rest of his life.
Mezzo, while the anon isn't kind at all, taking stray yukkuris in your home isn't exactly a good idea, it's better to avoid them, kill them if they get annoying or clearly need the mercy kill, or let proper specialist deal with them, either breeders, pest control, etc.
You'll find yourself with way to many problems trying to raise strays if you aren't just breeding them for torturing them and their next generations.
When most anons hate them by default without reason, it's unrealistic expectations to expect them to take in gutter trash even when they're sympathetic. Might as well have fun with them! Very kind in comparison to what he could have done to them, though.
