Nothing justifies burning dogs
Not even Doom music
But seriously though, how are people so heartless as to just set a random animal on fire just for entertainment? They're living, and breathing creatures that have feelings, they're not toys, it's not like it doesn't matter whether they die or not, because it does matter, they could have died in a more dignified situation, had a home and lived a good life, or just lived in the wild where it feeels happy and free :(
