Even that’s still a very different scenario. Survival for you/your family, vs intentionally dooming a defenseless, sick animal to a slow, painful death (or laughing about it, in your case). That’s not a stereotype, that’s basic human compassion and empathy.

In your first example, euthanasia is far better than “tossing a sick animal in the trash”. Obviously. Anywhere in the world, no matter the poverty level, there’s cheap, quick, humane ways of ending an animals life. And yes, I would do it personally, if I had to. Intentionally choosing suffering over a quick end is wrong.
