True love/compassion/sympathy is ever required of you/everyone in order to make the world a better place. Oh! Yes, anyone who lacks any of the above virtues is just cruel/inhumane. You can say I said so.
Unless/Until you showcase your love to someone else/others you've not yet started loving truly. For, it takes two or more to tangle/tango i.e. the impact of your love ought to be felt maximally by someone else/others.
Virtuous motives, trammeled by inertia and timidity, are no match for armed and resolute wickedness. A sincere love of peace is no excuse for muddling hundreds of millions of humble folk into total war. The cheers of the weak, well-meaning assemblies soon cease to count. Doom marches on.
