God put a soul in your body which also functions as your conscience, if you believe you are innocent, your conscience is clear then Heaven awaits. God doesn’t judge you after you die exactly, the soul, the conscience that you have lived your life with judges you, so God gave you the tools per se to judge yourself.
IOW, after your death, your soul will either free itself or condemn itself. If man takes responsibility for his choices and his actions, then whatever man’s final decision about the life he lived is is justified by his choices, his actions, his very own condemnation, so God is not to blame for what happens in your afterlife, you are.
The real question is whether human souls will ever feel worthy of perfection? If you are your own worst enemy, you will fall from the possibility of grace which is perfection. Can you honestly make peace with your flaws whatever they may be and forgive yourself for being less than perfect?
