Disagreed. Religion is a tool for greater spiritual awareness. The fact some men have used it to do exactly what you said is irrelevant.
Religion has given great comfort to far more than it has been used for harm. The same goes for axes, guns, automobiles and other tools which have been misused and harmed others.
Granted religion can be used (and is) for spiritual growth and understanding, this aspect does not seem to be primary in it's practice and the harm it inflicts in physical and mental realities far exceed the benefits Sunday morning Christians claim.
