300 opening sequence analysis

The scene begins with the title "300" in a sketchy bloody font. It then goes to a man (who is known as a spartan) holding a baby (who then goes on to become the main actor) over a large cliff. At this point the audience would be tense as they are unsure if the man will drop the baby or not. There is also a medium close up on the baby's face to show its innocence.
The scene then cuts to a few years later when the baby boy has grown into a boy, he is being trained how to fight by his father. At this point the audience would be feeling shocked because it is not normal for a father to purposly train their child to become violent, at the end of the scene it shows the boy looking and probably feeling angry.
It then goes to show the father showing his son the spartan sheild and the boy (medium close up) nodding.
The next few shots then goes to the boy being subjected to a lot of violence.
It then shows the boy growing into a teenager and having to attack and kill a large wolf.
The scene then cuts to the teenager, who has now become a man, becoming king of sparta.
