I'm somewhat agnostic but this is pretty simple actually. God didn't "plan the death of Jesus". He accepted it. He knew the hearts of man and what would end up happening. People aren't puppets, we have free will. If there is this God, He obviously has no control over YOU. Right? God had no control over the people that tortured and killed Jesus either. COULD He control people? Of course, Hes God. Free will is what makes our lives individually meaningful, the opportunity to chose our own internal paths. God knew what would happen but also knew entering the world through Jesus was the only way to save us from evil. An earthly example: Someone sees a baby crawling in the middle of a road, about to be run over by an eighteen wheeler and realizes they have a chance to save this baby but would certainly lose their own life in the process. Saving the baby wouldn't be an act of suicide. Suicide is a selfish act that involves TAKING your own life because you no longer want to live. This person would be GIVING their own life in order to save the life of a helpless and clueless baby.
