Why do people kill..???

I always wonder why do people kill...
Is there any thrill.... You are killing someone you don't even know,
and nowdays these activities are going on with an uniterrupted flow
Is there any way to stop them or make them realise...
Or we just have to be a spectator of humanity's sad demise
who should be blamed for all these mishaps
Or is this all because wrong poeple have got powerful caps ?
power is a feeling which every human enjoys
Is it good or it always destroys ?

Criticisms are there all around the globe
But has anybody made a deep probe
As to why do these things happen

First we should give all this a deep thought
then only the solution will be sought

Or is it that nobody's is really looking for a solution
they all are just using all this for their promotion

Everything which our leaders say sounds so fake
Oh God ..please give them some brains to atleast do something for the humanity's sake

If the trend continues and terrorism goes on
no one will know when his life will be gone...

Is this the kind of world which humans desired
If this is the job assigned to humans, then I'd love to be fired.
