So in Deadpool 2 we see that Cable
travels back in time to save his family by killing Firefist, who kills his wife and daughter in the future.
To do so, he
enters the Icebox by force and fails because of Deadpool recovering his powers.
That made me think:
Deadpool was going to die in the Icebox, without his regeneration powers due to his multiple cancers. Cable's action leads to saving Deadpool's life, and forces to move the inmates in the Icebox to another high security prison, and Firefist uses that moment to escape.
So the question is:
If Cable didn't travel back in time, would Firefist be able to escape prison, kill the director and ultimately, kill Cable's family?
