Snakes are harmless unless you step on them, and Diana is like a snake, beautiful but repellent - and dangerous. And in fact Actaeon does not actually do anything, he merely observes and and unwittingly too, by doing so he is condemned to a hideous death, ignorantia juris non excusat , taken to the extreme. Diana turned him into a stag to be torn to pieces by his own hounds.
It set me thinking of John Wayne Bobbitt, his behaviour was less excusable than Acteon’s but then he only lost one limb - and that to be sewn on again.
