my first existential crisis as an exmuslim

just saw a video of a female dog and 4 of her puppies being shot, the mom and 2 puppies died and the two other puppies remain injured. in my country there are barely any animal rights (human rights are barely there either) so much so you can call the government if you see a dog around your house and they are gonna poison it for free. so i knew the dog shooter is just gonna live his life like nothing happened or maybe shoot even more dogs. now as an atheist you can really see how unjust life really is.
