“Do we have a better Criterion than the Book of Allah, of Right & Wrong?”
Sir, your statement hits the nail on the head. No human aberration is unbearable except that which is accompanied with consciousness of wrong.
By the way, according to NARTH (National Association for Research & Therapy of Homosexuality) there is genetic counseling and some aversion therapy that may cause changes in sexual orientation from homosexuality to heterosexuality. In one such therapy, gays are shown pictures of naked men and simultaneously given electrical shocks in related part of the body. I am not sure what the therapists say, but once repeated I guess it would be enough for rehabilitation or clemency or both. There are therapies for lesbian too.
