Sisi must continue to prove that he can hate the population enough and repress the people with adequate brutality. If he can, he will not lose the support of his masters
If rebels take the path of vengeance, it will help Sisi to carry out his role.
And broad based grassroots opposition will not materialise. The rebels will marginalise themselves and their numbers will shrink.
Liberation first, retribution against the traitors after; under a genuinely sovereign and independent government.
By law.
