Yes I could with varying difficulty to whom it was I was going to kill and under what circumstances. If I was a soldier and tasked with killing another soldier I would do so easily. If I had to kill a criminal because I was ordered to by anyone I would do it albeit even easier than the other soldier. IfI had to kill a stranger it would be harder but if you don't think about the man and only the life it becomes easier. If I was forced to kill a loved one that would be hard to say the least.
