Boon or Bane!

I see people with " big brains"!
Who always succeed to overcome their pains,
Somehow they tackle; but in the form of psued,stab or cheat!
Is this the way for the solution they meet?

Some "good ones" succeed to express their cruel image as smartness,
So that they overcome the game of weeness.
Unaware of the dangerous web, they wrap around themselves,
For beating and stabbing the innocent elves.

I wonder how they feel proud on the act of mixed,
By the victory they gain against the unmixed,
Observing all this, often the questions arise in my thoughts,
That if these "big brains" are blessed or cursed?
To be constantly getting trapped in their own mind crowd?

Its's definitely a topic for debate; "big brains"- Boon or Bane?
