Here's a scenario: I heat up a bag of rice and plop it down on or near a child - or an adult. The person screams out or cries out - expresses discomfort. I a) remove the hot pack, assess the injury and render aid or transport to hospital or b) try to cover it up to avoid culpability. 
Or: I press some too hot object onto someone because I can.
This seems like more than an accident....
