Even the Kahan Commission, a board of inquiry appointed in Israel to look into Sabra and Shatila massacre, gave Sharon the lion's share of the blame for the massacre and recommended that he resign or be discharged. In 2002, Sharon, PM at the time, ordered the assassination of Elie Hobeika out of fear he would reveal Sharon's major role in organizing the massacre, after Hobeika promised to testify at a Brussels court handling a lawsuit against Sharon for the massacre; Hobeika was at the time of the massacre head of the security arm of the pro-Israel Lebanese Forces militia, and Sharon's fellow perpetrator. And as for Sharon's role in the Qibya massacre, one needs only google Qibya massacre.
