As shown many times in the manga, Meliodas can't fight with some enemies with certain powers, as Ruin (ilusion) or Griamor (shield), so he fighting alone is more vulnerable to lose.

Also, Meliodas standard power is 3370, wich is (I believe) a bit more than that of a Holy Knight. So he fighting the two of them at the same time? well, that's already a big problem.

The reason Meliodas doesn't use his full power at all time is (besides his desire to try not to destroy too much) his fear to lose his mind under that massive power. The last fight showed us his suffering to overcome his dark side, not to kill everyone with him while trying to stop Galan.

His fear is born at the same point when his sin begins: Him, lost in rage, anihilating an entire kingdom including everyone in it.
