Two kinds of people who unite to do things

There seems to be at least two kinds of people who unite to do things.

One type unites to get the group to attack targeted others, so as to "win" something; that is, to deprive specific others so the united group can have all the goodies.

The other type unites to get people to build mutually beneficial things together, and/or responsibly maintain those mutually beneficial things, long-term, as part of the larger system of life.
