Very few countries operates on a majoritarian voting system, and the reason is often related to civil wars. If the highest populated areas has a overwhelming dominating majority then the low population loose confidence that their vote maters and is simply a wasted exercise. Too much of that and you get civil wars and nations that split into smaller ones that each operates more efficiently towards the needs of those living in each of those areas.

A big example of those is not a nation but rather EU parliament. Citizens of the smallest country count twice as much influence as the biggest country, and the reason is rather obvious to keep those members states interested to be part of the union even if the voting power is going to be minuscule compared to the big countries. Even so the sell is a tough one.
