Despite his disturbed state of mind, Max was rational in his approach of raiding planet Zika.
He did not just barge into planet Zika spells blazing as he understood the strategic importance of not letting Ulrich be given any chance to escape.
If he acted on his instincts and just started destroying buildings and military establishments from the get-go, he would not be able to find Ulrich who was more likely to run away than stay behind and fight in his current condition.
A big disadvantage that the modern vampires faced in this war was the handicap that they could not indiscriminately destroy planets like Dracula could.
Destroying a planet was not impossible for Max at his current strength, however, he could not do so when the planet in question housed millions of enslaved modern vampires.
