Because people want to scape from the reality and blame God for their deeds/actions.
Come On people, God doesn’t change person heart until and unless that person himself/herself wants to change their heart.
I am bad because God made me like this and with this statement we have thrown all the responsibility for our own actions and deeds on God. So whatever bad or wrong things I do its because of God since he controls my heart.
Take Responsibility. Open your eyes. He guides those who seek his guidance. He forgive those who seek his forgiveness. He changes the heart for Good of those who seek that change.
So only God can change that heart if you are seeking that change within you.
