Why do people/student torture animals- what drives them?
Can we analaysis and find solution: let try to stop this any more in our life
As we all aware that two animals cruelty incidents happened in tamilnadu, one with the dog and another with an monkey.
Case a, 12 yrs old kid hitting cat with broomstick, their parents brought for an counseling that he has not coutesy for animal and he was killing without any guilt.
Case b, 23 yrs adult was burning a rat alive with kerosine and feeling happy to see that rat die with burn.
And there are many cases which were not recorded and submitted for case discussion.
What typically possesses them to inflict such acts of intentional animal torture and cruelty? 
These are because of psychological disorders (such as anti-social/psychopathic personality disorders and engage in deliberate acts of zoosadism), and/or because they have sexually paraphilic disorders (such as crush fetishism in which small animals are crushed for sexual pleasure). 
This may be common behaviour among murderers and rapists - those with psychopathic traits characterized by impulsivity, selfishness, and lack of remorse.
Animal torture and cruelty is one of the three adolescent behaviours in what is often referred to the homicidal triad , the other two being persistent bedwetting and obsessive fire-setting. The combination of two or more of these three behaviours increases the risk of homicidal behaviour in adult life.
The behaviours in the homicidal triad are often associated with parental abuse, parental brutality (and witnessing domestic violence), and/or parental neglect.
What we can do:
The best way to prevent it is teaching by example. Parents and teachers are the key and plays very important role.
Pro-social behaviour (action/behaviours intended to help others) by parents and other role models towards animals, such as rescuing spiders in the bath, feeding birds/ants, treating pets as a member of the family, 
Schools and colleges can have some pet home in the campus.
These activities or act has the potential to make a positive lasting impression on children.
It's a start, lets all have at least one pet in the home make your son/ daughter to take care of them (pet therapy).
