Lololololol I can see that you're triggered like a landmine, but since you seem so intent on showcasing your piss poor grasp of the English language to everyone, let me break it down to you.

If I had intended to "threaten" you, I'd have said something along the lines of "I'll kill you, you absolute fucking illiterate". The presence of the first person pronoun and the modal verb in that sentence should clue you in to the fact that the subject(me) here is different from the object about to be butchered(you).

In contrast, what I did say in the original comment was a mere "End yourself". Neither having a first person pronoun nor a modal verb. Instead there's the reflexive pronoun 'yourself', implying that both the subject and object of this sentence are one and the same.

As you can see, it is as unambiguous a sentence as can be written which you'd have understood if not for your astounding incompetence at reading comprehension and if you had passed sixth grade English grammer.

End yourself in shame, you monumental fucking nonce
