Well, let's see.
Anything.
Yes, that sounds right. You killed a fucking frog. A species of animal sometimes used in scientific experiments. And that's the best rationale you have yet to offer for how this is "scientific"- which wouldn't be a justification by itself in the first place. In other words, you're not only a sicko, but a none-too-bright one who honestly thought someone would be amused by you gutting random animals for no apparent reason. Or, at least, buy into the idea that any form of killing is somehow justified in the name of science, even if it has nothing to do with experimentation or anything else but a bunch of dim 15-year-old crackers chortling over the spattered remains of whatever didn't run the fuck away fast enough.
Might as well quit while you're ahead, smart guy- you're letting a little bit too much information about your personality get out.
