Galactus is a parasite of cosmic-scale, what you view as evil is necessary for his survival.. this is why Xenomorphs can't be classed as CMs.. also with Galactus he is often seen as a force of nature so his evil is akin to the "evil" of a destructive storm or hurricane.. he is also destined to actually recreate the multiverse when things end, is connected to all reality and if he ever dies fully the far more nasty Abraxas arrives..

Galactus can also show mercy at times and even very brief friendships - in Marvel you'd find Mephisto, Green Goblin, Carnage and Apocalypse to be more evil in their cartoon incarnations.

Though as you said, CM is a personal opinion and you can think whatever you wish.. just know that Galactus is much like Beyonder - neutral.. they are both on this wiki because they are capable of vast destruction and are dangerous to many heroes, not because they are fully malevolent,
