Atheist You are a Soul and Your Brain is NOT your Soul So Yes Death of the Brain is Death BUT?

Your soul is YOU. You all claim that when the brain dies we are dead. Basically We Are Our Brain ? I disagree. What if a person thinks evil thoughts but does not carry them out Does that make them Evil ? Goes to show that Our Brain is of this World Imperfect we are born Imperfect aka sinful. There is no perfect human. Goes to show we have and are a SOUL. Our Brain is not who we are. If that's the case are u Your Dreams ? The brain will die. What you are (Your Soul/Spirit) and I hope that is good will NOT Die after death of the Brain
