If we go to Hell on default for being inherently sinful and wicked in the eyes of God?

No It doesn't, God Himself knew that Man could not because of his sin nature could Fallow His Commandments, Sin Had to be punished, someone had to pay the price, so He became Sin for us in Jesus, Who took that penalty for us, He became the sinful and wicked on our behalf, all you need do is accept His free gift of Salvation, You cannot do enough Good works or deeds or Grovel at his feet to Obtain approval, You already have it regardless, Jesus did that for you
