Yeah, but that was 'just' an accident. He didn't nearly die because he is a bigger doper than the rest, this could have happened to anyone.
I don't really see a comparison to Pantani. Pantani was a coke addict even when he was cycling, he had severe mental problems, nearly unlimited funds, no social support, surrounded by vultures who wanted to keep him on his bike so they could earn some momey of his fame etc. Non of that applies to Riccò.
Of course he
could have mental issues (narcissism at the very least

), but we don't know that. For all we know, maybe his decission was completely calculative: ''I have a wife and child I have to take care of, the only way I can have a succesfull career and make a lot of money for them is by doping, so I'll take that risk'' .
