The IDF solder who killed a disabled Palestinian should have been convicted with murder because this make soldiers be more less hesitant to react to potentially dangerous situations. It is obvious the soldier pulled the trigger because he felt his life was in danger and given the that Hezbollah are using all manner of tricks, he could not have left anything at chance.
No, this conviction will not make soldiers less hesitant to react to potentially dangerous situations. The conviction of an IDF soldier for killing a disabled Palestinian will make soldiers more hesitant to react to these situations because this solider was punished for doing so. If he weren't punished, it would potentially make soldiers less hesitant to react.
No, contacting this IDF soldier of manslaughter will not make soldiers less hesitant to react to potentially dangerous situations, because they are now afraid that they will be put in prison for doing their jobs. It is easy to look at at soldiers' actions after the fact, in hindsight, but they have to act in a split second. It is too hard to second guess.
I feel that a soldier being convicted of killing someone who was disabled would tend to make soldiers MORE, rather than less hesitant to react in potentially dangerous situations. One will be far more likely to face public scrutiny when determining if the killing was at all warranted when the person killed is disabled.
