He broke the law, that's a fact, but I can't imagine someone getting a life sentence in any European country for creating a website. It's restricted only to most dangerous, hardened criminals. Even murderers get between 15 and 25 years in prison.
It was more, far more, than just a website.
And the chances are that if he'd been another nationality he would've wound up being extradited to the US anyway.
Anyone who runs a dark market now will get a few years. Anyone who was the first to do it would've been in bottomlessly deep shit no matter where they are. Very true, it was pretty obvious that he was to be made an example for anyone trying to copy him.
We all saw how that turned out

They basically cut off the hydra's head and several others came in its place...
The sentencing is just ridiculous imo, even if it was true that he
tried to have people killed.
Sure, attempted murder should land you in prison for a couple of years at minimum, but a life sentence is too much even for those serious accusations.
Just my two cents though... I'm sure that people will disagree.
