Well, if you don't crash because of erroring entities, it is possible to do a lot of damage to your world or more. Not that that is terribly likely, but it is still a risk. Minecraft crashes because something throws an error, and it crashes so that the error does not cause any more trouble. This basically says "don't crash because of these".
