Not remotely, go read the studies as I have pointed out.
Back before and during WWI the army trained rifle practice with standard round bulleyes... What they found out in battle is that a moral and decent human being would often hesitate to pull the trigger when faced with a live human target... They switched over to sillouette targets and found that the hesitation factor dropped significantly...
Modern first person shooters are just more mental conditioning to shoot without thinking when faced with a real life situation.. or desensitizing of the humanity of the act. This is well documented.
