wasteful ...... well let look athis shall we there are two ways of palying the game killing and none at all or mixture of the two each has it own level of skill to do stealth take time can be tedicous at times good way of surpising enemsy greater than 1 of them it take more time to knock them out that just kill them on the spot if the body is found they are woken up and may not raise the alarm or there going in head first in toa cshit storm it all about point of view second then you fell for the trick thegame is about self control and you clearely failed at that why give you the option not to kill anyone at all ?
