Obviously, to you, there is no line that the courts can not step over before the executive exercises any kind of check on them...not even killing citizens by cruel and unusual means.
It's not the executive's job to check them. That's the job of the legislature. If they are doing something wrong, they can be impeached. In Florida, they can be recalled, I believe.
Separation of powers certainly doesn't seem to mean much to you if it doesn't get you what you want. It is your 'interpretation' that the court "killed a citizen by cruel and unusual punishment", it's not a 'fact'. Fight for your interpretation, don't declare it to be absolutely true. You aren't a dictator, regardless of how much you might want to be. You need to convince other people you are right and change the system through legitimate means.
Like most fanatics, you can't wait that long.
