So I changed the event so now it's just (health being a skill I define at the top):
Code:
function delete()
{
	if (event_type == EVENT_IMPACT || event_type == EVENT_ENTITY)
	{
		wait(1);
		my.health -= 1;
	}
}

and put the rest of the stuff into the action of the entity, so in the loop I have:
Code:
if (my.health <= 0)
		{
			if (you)
			ent_remove(you);
			ent_morph(me, "death_model.mdl");
			destroy_percent += 10;
			ent_animate(my,"deleting", destroy_percent, 0);

			if (destroy_percent >= 100)
			{
				wait(1);
				if (me)
				ent_remove(me);
			}
			wait(1);
		}

now it finishes the death animation and then exists the game.
Putting the remove(you) command into the event doesn't seem to change anything
