2) Control is trying to do exactly what the Leviathans tried to do, thinking "this time it will be different" which is pretty much the same logic they used too. This is aside from the general badness of using the Reapers to control teh destinies of others.
No it's not, not remotely. The principle flaw that led to the cycles is simple - organics try to control synthetics and eventually fail, because synthetics inevitably recognize their flawed nature and consider their orders invalid. Just as the innocent and helpful Geth unit from the consensus archives began ignoring shutdown commands seemingly for no reason.
Pure organics cannot hope to command synthetics long-term, because we are fundamentally inferior to them. Even the odd organic who is considered to be a superior source of orders (like Shepard) is still mortal, and will one day be replaced. Meanwhile, Control and Synthesis work because they address this root flaw - either placing an immortal synthetic in charge of the Reapers who desires to discontinue the cycle, or by removing flawed organics from the equation entirely.
The Catalyst tells you this itself - the Leviathans were flawed organics, who "could not see that their deaths were part of the very solution they required." Simply put, any attempt by organics to use synthetics long-term is doomed to failure, but the advantages of synthetics are so myriad that we will never stop trying and making them. It's a hopeless situation without synthesis (whether gradual or Crucible-induced), and the problem pops up so quickly once we reach a certain technological threshold that gradual synthesis may as well not be an option.
