Am I Merciful ?

Just now , i was playing a war game , it was based on the romance of the three kingdoms , which is my strongest era in war time in terms of strategies . I started with 2 other computer players . I set them to hardest . I started off by trying to get alliance but got rejected . then the other 2 gang up against me . They send huge armies like every 5 mins , mind you two kingdoms against 1 . Of course they could not even get into my city after like attacking me for 1 hr or so . then i got bored . I tried to get them back to peace again and end the game . They felt that that was the sign that i cannot hold any longer . Until now i should be counted as merciful , I had troops that can swept through the other 2 kingdoms in no time . Then they reject me , even the money i gave them . I got damn bored and fed up and I send out my troops after they next attack , which was their last . the game ended then i look at my stats , i killed 3000 armies while they only killed 200, sorry is 20 not 200 , of mine . After 1 hr of bombarding me and after my army swept through them . Am I merciful ? If i swept the 2 kingdoms earlier i will be cruel to them but i would have saved 3000 armies and their family . Am i a merciful and clever angel or am i a clever but evil devil ? Although they are fake people but lets treat them as real human , RIP .
