It's my lunch break and I decide to go on conwylia to see a religious debate unfolding. I figure I should seriously input my opinion on the matter for once.
The concept of lust being a sin is broad and technical. I cannot speak for other religions and their policies but my own personal views are that feeling arousal for something is not going to be a catalyst for damnation. Having that lust influence you to perform horrid acts that hurt others is a problem.
Also the concept of judgement day and hell. I do not believe in a conventional burn and suffer forever hell. That accomplished nothing. The man doesn't learn a lesson that he can then put to use and better themselves with. Hell is forcing to acknowledge the horrible actions you've done and then feeling the guilt for it, not eternal torture.
