I dont think that's particularly realistic to expect.
part of the transitional phase to communism involves implementing systems to ensure that people don't have the power to exploit others. it limits the amount of harm that people can do
I've seen the "it goes against human nature" argument against communism (to which I assume you are referring) hundreds of times, and it never gets any less stupid. capitalism encourages people to be greedy, to exploit others. it stands to reason that more people will be greedy and exploitative than they would otherwise. it's important to remove that incentive during the transition between capitalism and communism. part of this is making sure that everyone has their basic needs met: if it's not necessary to compete against others for survival, those attitudes fall away pretty quickly
