Chill out people. Just because the OP's friend wants her fish to die doesnt make her an evil person. She's probably uneducated about them and she doesnt think their lives have much value. I mean, I have gone fishing before and if that makes me a cruel fish murderer then... ok I guess I am. Its not like she likes stabbing it with a fork lol. My little brother used to do that a few years ago when we had a betta in vase. >
But if she's cutting open her fish, cats, and dogs, then ok she definitely has issues.
