The recoil is going straight back from the barrel. However in order to get the shooters eye in line with the sights the stock goes bellow the line of the barrel. So the recoil is not in line with the support of the shoulder and is therefore rotating the gun upwards. Even if the stock were in line with the barrel the recoil from the gun would also bend your back, hips and even push you off your feet.

The compensator redirects some of the gasses from combustion upwards. This jet will then push the mussel of the barrel down countering the rotating forces of the recoil. You still have the regular linear forces pushing you back but at least the barrel stay on target for the next shot.
