Some people just think that way, it's very hard to change them, they're just naturally desensitised or insensitive to another being's feelings :(
I don't understand though, why people insist on having pets (especially fish) if they don't really care.. What's the point of a pet if you don't care for it's well being, so much so that you're contemplating flushing them alive... Isn't there at least the voice of common sense saying no, don't do it?

Betta love: it's an international thing.
Azure, Sterling, you will be with me forever. Peaches, my crazy girl, I'll miss you the most.
