There are tons more videos from where that came from. I think even if you made a petition, the most effective one would be to just make youtube put one of those "Violence-Viewer discretion advised" and those things to at least let people know its something bad. & even if you did propose this to them, non-fish-knowledgable people would probably say "Its in their nature for these fish to fight." and if they're really pathetic they might even say "Its educational. Its nature. Live with it" or someting like that because that's usually what petstores do. But telling people you wish they were the betta being killed kinda makes you the red betta and the person the blue one if you kinda understand what I mean. Words hurt just has much as physical actions and just because you know its wrong doesn't mean you have to "return the favour" and hurt them back
