A devil is the personification of evil as it is conceived in various cultures and religious traditions. It is seen as the objectification of a hostile and destructive force.
The devil is real but we should not see him as powerful because he/she have attributes we don't want.
The attribute in the devil is weakness and make us to destroy him/her from our life if we know what it is that make them weak.
