I don't doubt that at the time he said he wouldn't commit suicide, he meant it, but based on other tweets quoted among these comments, he was very clearly in a state of depression brought on by his incarceration -- and, for god's sake, he'd spent most of the last decade as a fugitive. This is a man who went to extreme lengths to avoid being in prison. So when you keep asking, over and over, "What makes you think he would possibly commit suicide to avoid spending the rest of his life in prison," the answer is "literally everything the man had been doing before he was caught."
There is so much reactionary outrage online that people accuse you of supporting a belief for simply discussing it even if you didn't push it and haven't committed to it.
