He basically imprisoned himself for all of those years. And what's worse - those years won't be subtracted from whatever sentence he's going to get. I don't understand what his long-term plan was.
Yeah, but without a proper exit plan - you're only delaying the inevitable.
He has spent 7 years in the embassy and 4 years in an UK prison - and his trial hasn't even started yet. 11 years and counting - many murderers don't get that much.
