I got to give credit to M Ravi for working very hard for every 'human rights' case but his motive remains questionable and somewhat lack sincerity. As you said, this case does bring in lots of publicity and if Vui Kong was pardoned, he will emerge the "winner".
I am sure Vui Kong do know the strict laws here, hence he was prepared to die. Some opportunists from the Opposition are using this case to showcase Prataman and PAP as "heartless, bloodthirsty murderers". It is natural of SDP to jump on this bandwagon and champion their "human rights" and Western democracy ideals.
I am peeved that the supporters and friends of Vui Kong seems to be blaming the PAP for their problems when it is obviously, the fault of Vui Kong for succumbing to temptations of quick money. Even the parents seem to be shunning their responsibilities and quick to push it to the Govt. Vui Kong is no dumb, naive innocent twit. He did it several times before getting caught and he earned money for that. If he had not been caught, only Heaven can tell whether he will be living in a nice bungalow with many cars while breaking up other families with his drugs.
