Why do they b*tch around?

I do not conclude things unless I have enough evidence. I have seen enough to ask "Why do they b*tch around?"
There are these lovely ethereal maidens, principled, disciplined and sweet. But you change the directions, and they take a dip in the swamps pretending to not know the difference between the clear waters and slush. They travel miles away from home and indulge in such hideous acts that they would not have otherwise dared. If this isn't misuse of freedom, what else is?
Outrageous acts of indulgence in alcohol, smoking, indiscriminate sex and even drugs are gaining limelight. And worse, it's from desi girls coming to study abroad. As usual reasons galore to support this absurd indulgence, but all of us know that reason is a mere mask and a placebo to support a weak cause and convince a nincompoop.
Frustrations and feelings of dejection may derange a mind forcing it to act in unexpected ways. Remorse ensures that acts guided by a deranged mind do not happen again. But this is not the case I am referring to.
Even though arguments do come up saying that they are not habituated to any of this nonsense, and so it has not been a bad deal, I would like to ask why the indulgence when you know that it is 'nonsense'? I think it's more like throwing a deprived beggar into Ali Baba's cave. A case where independence and freedom have been thrown from the skies above all of a sudden and they have no clue as to what can be grabbed. They end up committing to sh*t and later come up with reasons to cover the trash pile. And worse, they continue so that their acts match up the reasons they gave and reason out more to support their act. So here, we have a vicious circle.
I do not wish to point my finger at the female gender alone. The other gender is worse still. But this is happening and these people are cheating themselves in their vain efforts to cheat others. Even after saying all this I would like to ask this one question - "Why on the hell do you b*tch around?"
