If your point had been that she took a risk by protesting because the IDF is known to kill protesters on a regular basis you would have been right. This is however not a fault of the deceased, that's like saying that a rape-victim is responsible for being raped because she wore a short skirt or that a victim of an assault is responsible for being beaten up because she should have known better than to walk in that area at that time. Your extremely illogical point seems to be that people who protest against abuse by the state are responsible for the violence that the state might use against them. This does not go very well with the democratic principle of freedom of expression. Bad judgment on your part I would say.
