Civilian casualties Vs. militant/military casualties

Here is the data provided by Israeli human rights group B'Tselem regarding the number of Israeli and Palestinians who have been killed during the 3 years of Palestinian uprising:

Israeli deaths:
794 total
(99 minors)=(12.5% of the total - Faramin)
(246 security forces)=(31% of the total - Faramin)
Palestinian deaths:
2,201 total
(398 minors)=(18% of the total - Faramin)
(207 "targeted killings")=(9.5% of the total - Faramin)
Suicide attackers:
129 Palestinians
Israel's prisoners:
5,278 Palestinians
(528 "administrative detainees")

According to this, only under 10% of the Palestinian casualties are resulted from Isreal's targeted killings, and the rest (over 90% including 18% minors) are civilians. Meanwhile, 31% of killed Israelis have been security forces and about 69%(including over 12% minors) are civilians.
Although no killing of the civilians, especially children, is justifiable, this data indicates that Israelis have been less successful in killing the Palestinian militants compared to Palestinians killing of Israeli security forces. I have to add, although it is the actual number of the killed that shows the dept of the tragedy, even proportionately (in addition to actual numbers), Israeli actions have been more devastating to the civilians.
This data does not even include "Deaths of Palestinians following Delay in Obtaining Medical Treatment because of Restrictions on Movement during the al-Aqsa Intifada" which adds up to 38.
