Ariel Sharon dies at 85

With regards to the second, if your aim is to push the Palestinians into ghettos, then land which you want to grab is worth more than the giant ghetto aka Gaza, especially if control over the west bank is more important in the strategic sense.

That doesn't quite address my argument. Your argument was that the land evacuated in Gaza was worthless. However, had it been entirely worthless, presumably the settlements wouldn't have been created there so at minimum the locations which were evacuated had some worth (and BTW, worthless for what? Some of that land is arable, the rest can be used for hings like greenhouses or housing, industry, etc.; we're not talking the middle of the Sahara here). Whether or not there is land which is worth more in the West Bank is irrelevant because it's not an either/or proposition; Sharon could simply have note removed Israels from Gaza, or, alternatively, removed most of the settlements but lopped off the Strip's northern tip and retained the three settlements there. There was a lot of speculation that he was going to do so; the costs of keeping those settlements would likely have been almost identical to the cost in the actual situation where Israel completely evacuated the Strip.

And yet, he also approved the wall

1) The barrierwas not first proposed by Sharon (for that matter, limited barriers had already been built as early as the mid-90s)
2) Sharon initially objected to the barrier. He was pressured into it by both his coalition and a grassroots campaign in support of the plan, following the high amount of terrorist attacks in 2000-2002.

and did nothing to reign in settlers in the west bank.

Besides kicking a not-insubstantial amount of them out, which I'm sad to say is more than most other governments in the last two decades have done.

What is supposed to be the end goal of Israel here?

At least under Sharon, the end-game was (based on statements) supposed to be a Palestinian state, and the disengagement was a concrete step in that direction.

Under the current government? Beats me, I have no idea what exactly their end-game is and I'm not convinced they know either.
