If I don't want you dead, but want to do something to you that that could kill you, and I do it, and it kills you, are you not still dead? I may not have intentionally tried to kill you, but the result of my actions would have killed you.

Some/most (all?) marchers didn't want to keep him in power, but the result of the march, if it was successful was that it would have kept him in power. They still decided to march. The successful result of their march would have kept him in power.

See?

It doesn't matter why they marched, the result of the march, if successful, would have kept him in power. People still decided to protest. They must have accepted that keeping him in power would be a by-product of a successful protest.

If you (or anyone else) still doesn't see my point, then draw a line under it and move on. I can't re-iterate it any more.
