How about that, even capitan_kerryfugio can figure that one out.
The wild, whacko, insane Radicals gained from the assassination.
The South lost due to the assassination.
The Radicals celebrated and had their way for a while.
Booth's diary was suppressed for years and when released had many pages missing after being in the custody of Stanton.
Who gained? The Radicals.
Who had motive?
It's truly funny how many things disappeared while in the custody of Stanton. Another famous example is the Dahlgren paper. It's existence was well documented under the custody of the confederate government and it is known to have arrived in Washington with the other surviving confederate government papers after the war. Then Stanton sent for it and it was never seen again.
Given your penchant for hysteria and nonsense, I am not surprised you actually believe that Booth was the dupe of the "Radicals."
Wow, it is tinfoil hat time!
