kuriakose thomas.... Yes, I do believe most, atleast 95%, of christians and muslims believe in sacrificial killing of humans.
More wives and girlfriends are killed by muslims and christians each and every day in many christian and muslim countries for minor reasons, than were ever killed as sati by hindus.
Christians do not allow women to become priests. They can only be nuns.
Muslims allow men to have multiple wives, but not the other way around.
In many muslim countries women are not allowed to even vote. In many christian countries, including america, women were not allowed to vote up until 1920.
