This guy deserves more than what we can actually do to him. In a way, it seems as though death is not enough. I hope this is not in poor taste because it is not meant to be, but Bane's line in the TDKR fits this situation perfectly..."[his] punishment must be more severe". While death is warranted and appropriate, I feel like he should have to endure a little more before his flame is extinguished for good.
