Is it normal to be upset when a neighbor does nothing for their dog

"My neighbor is not a bad guy, I think he is just not a capable pet owner."
I like that you can realize this difference. because just like some people shouldn't have kids, some shouldn't have pets either.

I grew up with, among a dog and cats and occasional budgies, two read eared slider turtles. whenever I went to the beach I'd make sure to collect these tiny hermit crabs and bring them back to feed my turtles and I vividly remember how madly they'd swim in their aquarium when they knew what I was about to feed them. feeding them those crabs would make my day, but over time it made me sad. because I realized how cruel it is to keep aquatic animals, or any animal that needs to be caged, just so someone could fancy up their home or whatever. I'd still love to have pet turtles but I won't unless I could have a dedicated pool or some sort of outdoor artificial pond where they have tons of space and freedom
