\kill self at any time? Maybe, it could be abused. For example, a player could kill himself causing guards to loot his body and thus allow pkers to wreak havoc elsewhere.
Of course everyone would do that and have their things looted
smartass, a player abusing it wouldn't just carry all his items. He'd tent them all but a few shit items and then do it.
Couldn't he just shoot a guard and effectively do the same thing? And in that case, it would even take a few seconds longer because the guards would have to kill him.
