Something like the way a loving husband and wife might get together to make that beautiful, bouncing, baby boy. They love that kid, and do the best for him all the while he lives with them. Then he goes to college, gets some weed, becomes a rapist, murders some folks, goes to prison. Mom and Dad didn't do it. Didn't have the slightest part of it in mind for him. The kid made choices, and they weren't in the programming the parents brought the kid up with.
