Reed's philosophy was that Victor would be better without Reed around to brood over. Victor without always trying to upstage reed would have a better shot at being the good person he supposedly could be. How the four relate to Doom and who knows what matter here. Whatever crap Reed pulled on Victor as recounted in M2i1 should matter. Ben's actually gotten some respect for Victor through M2i1 and Infamous. Who knows what Sue know about Doom and Secret Wars. She may have an opinion on that.
Doom's obviously pulling something. It doesn't seem to be a secret to anybody and we don't believe Galactus just showed up for a midnight snack. The question is: is Doom doing a good deed in an evil way, or is he a bad guy with good intentions. It may very well be that Doom is in the right and the FF will stop themselves before making things worse.
And Victor should know that telling Reed to stay away from a Doom/Galactus throwdown in Latveria is practically sending a limo to pick the FF up. I can't think of any FF villain who wouldn't realize that.
