Aye, any Israeli who isn't actively opposing the settlements in the West Bank is unambiguously in the wrong. And I wish that wasn't a controversial statement.
You're right in that Rabin's assassination wasn't the change in itself (that such Israeli extremists had continued to exist shows that that violent current in Israel had continued and been bubbling away), but it makes a good mark of a turning point and the loss of really any chance for reconciliation in at least our lifetimes.
When you think about it, anti-corruption laws are just socialism getting in the way of fair and liberal use of money.
