Okay, I can understand Jonathan's point at the start, Clark is being something of a pillock.
The narrators logic at the end is insane though, from what I can work out, it means; "If Jor-El had been focussed on saving as many people as possible instead of his son, he'd have been doing the right thing". Except that Jor-El TRIED to save as many people as possible with his, he was forbidden from doing so by the Council.
Personally I always thought spending his last minutes on Krypton flying around with a very large Phantom Zone Projector attached to his flying car would have saved a damnsight more people with a lot less effort)
