A Poison Tree Steaminess Rating

Exactly how steamy is this poem?

PG

"A Poison Tree" isn't a sexual poem at all. It is a bit violent, though. Even though it's never clearly explained just how the speaker's enemy gets laid out under the tree, we're guessing he's not taking a siesta. Add to that some creepy gloating over the body on the speaker's part, and you get a perverse element that isn't sexual, but still disturbing.
