Its basically Moriarty talking about detective meta that hinder him from victory against Sherlock.

In detective story, the detective is always prevail on solving problems (not about defeating the mastermind, just simply ruin the mastermind plan). Moriarty, with pride as Napoleon of Crime, can't keep accepting such fate over and over again (like EMIYA is tired working as CG, he is pretty much sick with idea of him keep defeated by Sherlock on many works).

The line "Its because you're an ally of justice too" is delivered following Moriarty confusion about how he still can't win even after he managed to defeat Sherlock; his plan is perfect, why it failed? Guda (and Mashu) answer that believing that Moriarty lose must be because his own desire for justice.

Moriarty, spending time with us, experienced how does it feel to be 'main character that fight in the name of justice'-- resulting on him unconciously holding back against us, trust us to defeat him and Baal, resulting on 'justice prevail' ending that he tried to crush with his plan.
