Q1: Can I process the part of the effect after "then" in this card's When Attacking effect even if the "if" condition in the 1st process isn't met?
Yes, you can process it. Even if your opponent has a Digimon with more digivolution cards than this card, this card's When Attacking effect will still give all of your opponent's Security Digimon -6000 DP for the turn.
