Tension in Jerusalem

"This is very clear evidence that Israeli soldiers are committing field executions documented by cameras against Palestinian civilians," -Dr. Jawad al-Awad, Palestinian minister of health

Video of an unarmed Palestinian man being executed on the street by an Israeli soldier captured by Israeli human rights group B'Tselem has surfaced causing people to question the ethics of the Israeli military. Two Palestinian males attacked an Israeli soldier in the streets of Hebron, stabbing him before both were shot. One was killed instantly while the other lay in the street, wounded and clearly alive. The Israeli soldier was wounded and sent to the hospital and is expected to live without any critical injuries. In the video it can be seen that the Palestinian attacker, identified as Abed al-Fattah Yusri al-Sharif is harmless and is in desperate need of medical attention. The 21 year old was lying in the middle of the street as medical staff and Israeli soldiers passed him by seemingly unaware of his existence until a few minutes later when a soldier fired a single bullet upon him at point blank range. The shooter was an Israeli medic who claimed he only did so in fear of the suspect potentially being armed with a bomb. The Israeli military along with government leaders like Benjamin Netanyahu have condemned the act.
"It is forbidden for a person, even when his blood is boiling, to lose his head and self-control. This incident will be dealt with in the most serious way. We have to know how to win and remain humane"-Israeli Defense Minister Moshe Ya'alon
Many Israelis are proclaiming the Israeli soldier who had fired upon the Palestinian as a hero. 

Questions: What should become of this soldier? How will the Israeli military prevent future abuse of power by its soldiers? Should the Israeli control over Palestinians be "loosened" to create better a better relationship in order to reduce tension?
