This is one Chinese policy that I feel the west could benefit greatly from adopting. Not the death penalty necessarily, but permanently life-changing consequences, surely.
Sure, but can someone guarantee he's not persecuted only for falling out of line of other corrupt businessmen supporting the ruling party, or that someone wanted to take his business? That'd be a positive life-changing consequence for those standing behind such a case.
No more than anyone can guarantee anything, but that's what court proceedings are for. I'm not suggesting that the government should have unilateral power to execute whomever they feel like just because they say they did a thing, obviously.
