Some people do change in a short periods after a violent events happen in their life, just a turning point in the path.

I think Salman when ppl changed fast its not permanent change ..
but u right some changed but Not for the better but for the worst & it will be very fast

OK

sure .. but this change not permanent & some ppl return back again & may be being bad than before

I don't think so may be i have a different experience

Sure & different ppl with different situations too

YES

YES

I think they can if they have experienced trauma of some kind Sama.

and if you notice any changes over short periods they are probably pretending!!!
