I read the comics so I’m not afraid of spoilers but it’s been a while so remind me if I forgot anything or if they explained it already.
Most empires expand to explore new world, gain strategic resources, visit new things, or even gain new cultures or customs. The viltrumites has been stated as been like the most perfect or powerful species in the world and they already don’t need to really eat are extremely powerful and advanced technology and can freely visit any planet with ease. They don’t care about other cultures, technology, food or knowledge or really need other resources, so what’s the point of expanding? Why have an empire? Why not just explore the galaxy and be not be just absolute bullies? What’s the point?
Expansion, power, access to more resources to obtain a better lifestyle to grow your wealth, build cultural moments, have people fight for you, to honor the gods, etc.
Yes, exactly. Why scratch your own back if you can get a slave to do it? Why farm when there is a planet filled with food right there. Why leave a perfectly good planet to those disgusting weak bugs, they cand defend it, they dont deserve it
Gods? You mean us the viltrumites? Do worship us
