No, you don't have to trust the miners because there are no known collusive schemes that would make more money for that volume of miners than playing by the rules would.
Maybe you think that some scheme will be discovered, but that's pretty speculative at this point. It's been many years and not a whiff of one.

Yes there is, coordinated conditional double spending on gambling websites.
There are also non pecuniary reasons to attack the network, such as vandalism (miners could be pressured into colluding by a government for instance)
