Do I need to cite chapter and verse to convince you that murder is worse than gluttony? That idolatry is worse than sloth?
Gluttony, arguably, hastens the death of the glutton and hence, it could be argued, is a form of suicide or at least a lack of respect for the gift of life.
Yes, in fact you do need to show me where it is written that some sins may be ignored or at least where the sins of the reproductive system are worse than sins of the digestive system.
