I do take evolutionary pressures into consideration in the list of reasons why this scenario is unlikely. I state that “highly intelligent aliens may be more likely to have evolved to be kind toward others.” However, it’s also possible that aliens “(or a group or an individual) have evolved to feel sadistic pleasure when they harm others who don’t belong to their group.”
Aliens who are excellent at cooperating with others may not necessarily be kind toward those who belong to out-groups. Lack of empathy or even sadism toward those who belong to other groups could possibly be selected for.
Additionally, there is the possibility that one individual alien or a group of aliens are sadistic.
Your point about resources is good. However, a highly technologically advanced civilization may have advanced to the point that they are no longer concerned about conserving resources. They may be able to generate energy with resources from many planets.
An intergalatic civilisation needs cultures that evolve for long periods of time separately to be peaceful with each other as it’s likely possible for one solar system to extinguish other solar systems if it desires to do so in a way that can’t be traced back to the attacker.
It’s a core economic principle that actors that are more effective at using resources outcompete actors that are less effective no matter the amount of resources that are available.
Thanks for your response.

Are you referring to multiple cultures that evolve alongside each other as part of the same civilization?
Your point about the economic principle is good.
