>>13674317Murder or assault is illegal everywhere in the world. You could argue that it is only illegal if frog man gets caught, but that will most likely happen anyways. He has no clothes to disguise his figure (in which case someone could easily notice him) or prevent skin, hair or other such things from dropping. If he also got a bit bloody in the fight (with his own blood), it can be used to track him, and I'm not even mentioning how he'll leave footprints and fingerprints on the weapon. In short, frog man will likely be caught and sent to court.
