If God takes over our minds to block out all negative thoughts, that would alter our personalities to the point where we aren't even the same people anymore. I don't want to be in a heaven with a bunch of mindless robots that aren't the people I've grown to love and care for. I want their full personalities to be there, their full mental capacities. I do not want to see our potential thoughts and potential emotions limited by a cosmic dictator who wants to restrict what we are capable of thinking or feeling. I do not want it to be a thought crime to feel sad about the suffering that other people in the universe are feeling.
