I didn't realize what this link was all about when I clicked it, but it absolutely tore my heart to shreds when I seen it; someone caught a mouse with a glue trap and gave it to a hoard of fire ants. I've been bitten by one before, one, and it hurt fiercely.
It scares me how "normal" this is among people. My brothers have tortured insects and vermin since they were little and are encouraged to do so; My grandfather has helped them stone trapped mice to death and my dad would put huge spiders in jars of poison for them to watch as they writhe and die. The video above is something they would do without ever feeling conflicted about, and yet they are good people otherwise and have always been.
I've asked them why they do it, but they never have an answer. They don't think it's wrong but they don't try to justify it either, they are just compelled to do it and seem to enjoy it. I don't understand, and it bothers me to no end.
