@cicerone imposter,
As an atheist I look at it this way.
Either I ignore the question as meaningless because the word "God" is meaningless,
or I decide to have a little fun with the Christian
concept of "God" by suggesting to them that "He" committed suicide. Such a game requires no ontological argument on
my part. The onus is on
them to juggle with their idea of an existential relationship between "God" and "Jesus" and to explain how the combination of these "prophetic" entities failed to have engineered the alleged crucifiction.
