There is no way of knowing if Fredo would set Mikey up again... but you cant chance it.
FWIW - Fredo wanted what Mikey had... so he would IMO set him up again
You just don't have your own brother killed. Especially one like Fredo. That was cold and heartless. He killed his mother's son, he killed his father's son.
Let me ask you this : Do you think that Vito would have had his brother killed had he been put into the same situation?
