It is true that we prefer to reach peaceful accords. Other races have other solutions. Humans tend to elect representatives, who then make laws and govern them. Krogan have leaders who rise through strength, though a clever mind usually helps. It certainly has seen Wrex unite them formthe first time in more than a thousand years. Turians rise through based upon ability. A people must find a method of governance that beat suits them.

Sometimes, even my people need to be lead with a firm hand. Often, it is a Matriarch who does this, because she is less frightened of offending people she'll live with for the next thousand years. It depends upon what the circumstances are.
