His term of cowardly seems to improvise that the good guys can even fight Cao Cao 100 vs 1 and still be considered courageous, just because they are justice. That is just bullshit. If i were to use your logic anon then i can basically start to call Issei a coward for using Riser's weakness as a Devil, I can even call Sona a coward for using her peerage as sacrificial lambs so that she can win.

Back then, when Issei fought Riser one-on-one, Issei wasn't doing it for justice, he was just doing it on his and Rias' own selfishness, and ignored other people's opinions. During the Rating Game in Volume 5, Sona was hiding in the back, and she used her servants as a front, even letting Saji get beat-up badly so that he can weaken Issei. I suppose this acts of are cowardly eh.
