He cold bloodedly murdered someone who was already wounded and defenseless - that is not the right side regardless of what that person had done before.
BUT... another point to consider is that the dead man was a combatant in war who was actively taking part in the hostilities and as a combatant he is a fair target.
I'm not saying I disagree with your post or your point of view, as I do think the killing of this particular combatant was uncalled for and morally and legally wrong. But the discussion falls under the conditions of war and should be considered under those conditions. (Hence war crimes rather than murder). Its complicated.
In another thread
we are discussing the justification of killing Israeli soldiers in a terrorist attack. The justification for that attack is that soldiers are fair game for killing -- even if they are not currently and immediately participating in hostilities.
Do you sense a double standard here? Are combatants legitimately fair targets? Are combatants fair targets only during their active participation in hostilities?
I don't sense double standards and here is why: the man who was shot was already wounded and down for 11 minutes. The objective was achieved, the threat is neutralized, correct? At that point, he should have been taken under arrest and dealt with. To then shot him in the head is an act of murder.
Your last question is complex and thought provoking. It's difficult to identify Palestinian combatents UNLESS they act...most are civilians and civilians are never fair targets. In a sense, any Israeli military person engaged in activities in the occupied territories could be considered to be actively participating in hostilities. On the Palestinian side - it's less clear.
No he was still a potential threat, more so than the Israeli children the arab muslims seem to target, so was still possibly armed and a threat.
It is only an act of murder if the act was pre meditated, as in the IDF soldier became engrossed in killing an arab muslim and
thought about nothing else for days or weeks beforehand. A spur of the moment act is manslaughter
It is not that difficult at all, just look at how they are dressed for an example. If they are wearing the checked headscarf then they are most likely hamas or fatah terrorists. If they are armed with anything that could be harmfull then they are militia.
So an IDF member patrolling the streets to keep them safe from terrorist, burglars, rapists and murderers is actively participating in hostilities, and not carrying out the demands of the Geneva conventions ?
