Spermbank,
If it was because of this man's state of mind (ie. lost), than nothing will stop these people. Punishing them with the most painful and horrifying punishments will not stop the fuses blowing in someone elses mind and doing thesame thing.
If it was, ofcourse, a pre-planned thing by a completely 'sane' (ie no fuses blown in the brain) it's a different matter entirely.
