Poor guy.
Imagine qualifying as a lawyer - spending years learning the legal system and full of hope and promise. You're going to change the world and make it a better place. Your life is spent working your way up in seniority until you land the ultimate case - prosecuting an ex president for fraud and corruption. You expose the lies and illegal manipulation and prove them beyond reasonable doubt. And against all odds, you win! Best day ever. Everyone slapping your back and telling you what a great guy you are, so clever, and this piece of shit is really going to get his comeuppance.
And then, despite knowing that they're voting for a criminal, half the voting people of your country still elect him into office, knowing full well that he's going to continue being the same awful human being that you proved him in court to be.
Justice, the system you've spent your life believing in and working for is pushed aside. The sentence is reduced to nothing - less than a starving person would get for stealing a loaf of bread to feed their family.
How the fuck do you continue after that?
How can you believe in any system that lets that happen?
Obviously he couldn't, and I respect that. I'd be heading into the woods to get away from everyone.
