It is true that, when questioned by God as to whether he ate from the forbidden tree, Adam replied "The woman whom you gave to be with me, she gave me fruit from the tree and so I ate.' (Genesis 3:12) Whatever Adam's motivation for saying what he did, God most definitely did not accept blame for the rebellious conduct of Adam and Eve. Nor did he forgive Adam, who as a perfect man, was guilty of willful sin. He sentenced the couple, saying to Adam "In the sweat of your face you will eat bread until you return to the ground. For dust you are, and to dust you will return. (Genesis 3:19) God then expelled the couple from the garden of Eden. (Gen. 3:23)
This sin infected Adam's offspring, like a deadly disease. So, all Adam's descendants came under the sentence of death. A Bible verse says "Through one man sin entered into the world, and death through sin, and thus death spread to all men because they had all sinned." (Romans 5:12) Since we were born in sin, we have a hope that God will forgive us. The Bible speaks about this hope at Romans 6:23; "The wages sin pays is death, but the gift God gives is everlasting life, by Christ Jesus our lord."
That verse speaks of death as deserved, "wages", but the everlasting life as a "gift" given to obedient ones by God.
