My modern history is pretty fuzzy, but the impression left is that Sharon was pretty much a tough Arab-spitting military hardliner. There's a nagging thought that he also went against orders to occupy the Gaza strip under Isreali authority in the '67 war.
Ariel Sharon appears to have been pretty much despised by the Palestinians - it was his visit near the Dome of the Rock in Jerusalem that sparked the second Interfada - which appears to help helped his grass-roots support.
However, as a politician, he seems to have begun with a mandate simply to protect Israel - but probable US pressure seems to have spun that mandate into protecting Israel, while offering concessions to the Palestinians.
Considering his prior history as a commander in the infamous 1967 war, and Palestinian hatred of him, Sharon seems to have walked a remarkably delicate line rather well - one in which he was at much at odds with his own government than against Palestinians. He does seem to have contributed positively to the peace process, albeit it with converse complicating actions elsewhere (ie, the land barrier).
Considering his somewhat fearsome reputation before entering power, he doesn't seem to have been as bad overall as could have been feared, and seems to have proved a rather flexible statesman.
Simply my own opinion.
