Here me this: you can not spread lies and keep a clear conscience.you know you perpetuate lies.you're not fooling anyone...if you killed someone your guilty !
Absolutely good point. If you lie about anything, part of your subconscious believes the lie itself. Part recognizes the lie for what it is. This produces a contradiction within. Is this contradiction what guilt really is? Is it the contradiction that wears on you, causing cycles of feedback in your brain until your brain can't properly direct your body anymore? Is this the real reason behind why we get old and die... we kill ourselves with lies?

Someone's conscience is obviously bothering them.For someone who murdered - what can they do to deal with the guilt that can follow? Only thing that works is the blood of Christ.
