This song is "Raise a Little Hell" From the Bonnie and Clyde musical.
It follows Wash during Season 7.
The cell was dark, isolated and lonely.
Given everything Washington had been through, he thought he would have at least been given a bigger cell.
Prison was horrible. It probably would have been more horrible for him if he wasn't also a highly skilled soldier, but it was still hell.
"I can't take no more of this./This nightmare has to end./In this God forsaken life/Death would be a welcome friend."
Wash thought of everything that had brought him to where he was today. Everything that everybody had done to him. He punched the wall behind him, looking up at the markings left there by the previous inhabitant.
"I've been betrayed more times than I can count/It's bull shit!/Now I'm stuck here for life,/Dying slowly bit by bit."
It's not like he deserved this or anything.
All I did was follow orders./Justice here don't fit the crime./I've been broken by the Devil./Justice is a waste of time"
It dawned on Wash that he would do literally anything to get out of here.
"I won't get to heaven./Why not raise a little Hell?"
"What makes you think I'm going to ask?"
Wash was a man with a mission. Apparently, the sim troops had never turned over the Epsilon unit. Another betrayal to throw onto the pile.
But this was different. This one was the last straw. If a couple of idiots could get the best of him, Was knew things had to change.
As he armed himself for his mission, he knew what he had to do, and was completely willing to do it.
"They'll see me but it's the last time!/Those reds and blues have gotta go!/In the end it will be over/When I strike the fatal blow!"
The old Wash would have hesitated. The old Wash would have sympathized.
The old Wash wound up in prison. The new Wash was going to clean his slate.
"Only way out! I gotta do this!/ Them or me, okay let's play!/Killed before, and I'm good at it!Time to make those morons pay!"
As he met with the Meta, the thing that had killed almost all of his former teammates, and as he watched the Meta terrorize the red soldiers in Valhalla, he didn't feel his resolve waver.
"I won't get to Heaven! /Why not raise a little Hell?/No way I'll see Heaven,/So let's raise a little Hell!"
In hindsight, this song could have fit Sharkface as well, but there something great about villain Wash. The more we learned about him in later seasons, the more we realize how threatening his arc in Seasons 7 and 8 was.
