Gacy was born on March 17, 1942 and until his death on May 10, 1994, took about 30 lives. Each target was under the age of 20 (except for one victim at the age of 21) and their bodies piled up underneath the floorboards of Gacy's home.
Gacy had a side job; that of being a clown at charity events. He named himself Pogo the Clown.
Similar to the Joker, Gacy never blamed himself for his actions, rather, his victims were to blame. No, he didn't stop there. He blamed all of society. As written in his psychotic report, Gacy, "presents himself as a victim...and blames others who are out to get him..."
What fascinates me is the fact that Gacy, while in prison, painted. His paintings were even sold to the public, unbeknownst to the buyer that the paint was applied by a psychotic killer. It's incredible to think how thin the line is between good and evil, so thin that it is impossible to distinguish between the two, in some cases. But here we have an example of evil, and he's behind bars...painting.
The Joker in The Dark Knight psychotically wished to prove that everyone was like him - alone, paranoid, and selfish. When the Joker commits a crime, he blames Batman for the crime. Every death is attributed to Batman, and it's justified, in a way. Batman lets the Joker live, obeying his vow never to kill - even the Joker.
But how many lives does it take? The Joker has killed the second Robin, something Batman lives with every day. He has paralyzed Batgirl with a bullet to the spine. He's killed Commissioner Gordon's first wife. Add that to the hundreds of civilians he has killed over the decades. And yet Batman let's him live. A quick trip to Arkham Asylum and then he's out again.
Which brings me to my next thought - the death penalty. Should Gacy have been lethally injected? My first thought was "Here is a man who has taken and sexually abused dozens of young men for his own demented reasons." We know Gacy's father was abusive. We know his background is that of pain and turmoil. Numerous times, Gacy had been under arrest and we let his insanity slip through our fingers.
Where do we draw the line of who to kill and who to let live? If we had another Gacy, if we had a Joker, should/would we allow them to live? Out of some self-proclaimed, self-righteous vow that "separates us from the animals?" Further, Gacy lived 12 years in custody before the capital punishment kicked in. What kind of speedy justice is that?
I think if Batman were real, he'd be asking himself this question every day. And the main reason why I love Batman is his inner turmoil; does he fight crime for a selfish reason? Does he allow the Joker to live because if he killed the Joker, is he just as bad as the murderer of his parents?
The Dark Knight Returns by Frank Miller isn't considered canon (or, the DC publishers have decided that the graphic novel is not the definitive ending to the Batman mythos). To me, it's as good an ending as Batman could hope for. Batman finally kills the Joker, realizing the countless citizens the Joker have murdered is something Batman should've righted a long time ago.
Anyway, this post was basically me ranting. Sorry for that.
