Okay but when people bring lyrics like that up he always said it's just art. In fact months before he died people asked him flat out if he was suicidal and he said absolutely not, he just likes writing about dark material.
But put that aside and look at the facts. The amount of heroin in his system would make it physically impossible to handle a gun. The shell casing was on the wrong side. The room was not barricaded. The suicide note was 100% forged and Courtney Love lied about where and when she found it. Also, Kurt was planning to divorce her according to several friends. AND the PI who was hired to investigate his disappearence has endless logs of her showing no interest in the entire event beyond money. What would you say is the most likely conclusion?
