There are only 2 facts to bear in mind; he was caught carrying drugs whilst in Singapore (forget transit, it was still on Singapore soil), Singapore has the death sentence for this offence.
I sympathise with your deeply held views and abhor the death penalty myself, but I don't have the right to impose those views on another society. Instead I can choose where to live, that is, in a country without the death penalty. Likewisw van nugyen chose to take the risk to make some money off other people's addiction and is paying the ultimate price for that decision.
