Here you have an apparently charming man who knowingly caused a great deal of violence and human misery with his trade.
His masterstroke[1] was having the audacity to blame the laws of the time for the violence in his trade - and getting people to agree that, yes, he has no responsibility for his actions, it's the laws that should be blamed!
And that's without even touching on his business associates; how you can call yourself Mr Nice while teaming up with the IRA and still look at yourself in the mirror every morning is beyond me.
[1] In later life. Staying out of prison by claiming to be an MI6/SIS informant was pretty clever, given that MI6 wouldn't even officially confirm their own existence until well into the 90s, let alone publicly comment on specific individuals and cases.
