Reading through the stories in the Chumash regarding Ya'akov and Eisav, I cannot help but wonder: could Yitzchak and Rivkah have done anything as parents to alter Eisav's negative religious tragectory? Was he destined from the womb for evil? Either answer poses trouble: If they could have done something different, then what did they do wrong? And if they couldn't, then that means that for some children, no amount of parenting can influence them. That I find difficult to accept.
