A Man of Weak Character more like

This documentary showed how nice, caring, upstanding and honest Dwyer was, but failed to point out the weakness of his character. Anyone can be nice when things are going your way and you get what you deserve, the real test of character is how you respond when the chips are down and you're a victim of injustice... and he failed that test in the most spectacular way possible. He revealed himself to be entitled, naive, hysterical and vengeful.
Extremely naive in that he didn't seem to know that you are not guaranteed justice in this life, sometimes life is very unfair and sometimes you just have to accept that you've been wronged, make the best of a raw deal and remember what's important in life i.e. your family. Dwyer put his family second to his burning desire to spite the people who'd wronged him. Never mind that his kids would be notorious because their dad blew his brains on TV, never mind that his family would be without their father, the main thing is that he stuck it to the people who plotted against him, what a tragic character.
He could have run a campaign from his prison cell over many years, maybe the truth would have come to light, it seemed like there were many people who would've fought his case for him. I think he couldn't face the possibility of failure and what he did was guaranteed to work.. well to achieve what was a productive outcome in his mind. You can elevate his selfish, vengeful act as an attempt to highlight the injustice in the system, but to hurt your loving family in such a terrible way to make a political point? And the bit about his family not getting his pension if he was removed from his post: I'm sure his family would rather have a broke father than any amount of money. There was no justification for what he did and it turned his honest life into a pathetic tradgedy.
