Religion or science

Cast in a pit, blasphemous words spit, an outcast
Scapegoat in a game of judgmental shame, crippled mind a body did outlast
Leather bands secure the hands of a man pronounced possessed
While in life's fever dream he did scream of visions that others distressed
A body convulsed, viewers repulsed, twisted words not understood
With a sharp stone chipped a hole in his skull's bone, releasing spirts for his good
Hear him shout as they come flying out, with blood evil spirits released
Making sure he received religion's cure, if not, better he be deceased 
Today instead of a rock we let people talk until they break the rule
Then deeming them ill give them a pill a pharmaceutical magic jewel
Those that defy we electrify or sever their brain with a shiny steel tool 
Now the walking dead, chained to a bed where they sit and drool
Some say it's better this way, science's treatment more humane
Have we come far to get where we are in treating the insane
