What does "The Destructors" say about human nature?

This question is certainly not a simple one to respond to
because it is evident that the presentation of the gang and its members is not simply a
caricature of delinquent youth. Greene is in fact very careful to explain their motives
and especially those of T. by referring to the post-war conditions of life that they
have grown up in. These children are literally children of the war in that they have
grown up surrounded by the debris of the London Blitz and in many ways they are victims
of the social upheaval caused by the war and the class system. It is also clear that T.
and the gang destroy Old Misery's house through no motive of hatred or revenge - think
of how they care for Old Misery during his night of captivity in the outside bathroom
and also how T. neither loves nor hates. However, images abound of hollowness and
rotting from within, which perhaps suggests that human nature needs an appropriate
context and setting with which to flourish. Given the bleakness of the setting, Greene
is clearly pointing towards the moral malaise that has occurred and its impact on the
youth who had never known a reality other than war and its aftermath. Thus,
respectfully, I think this story paints no clear message of human nature, but instead
looks at the impact on human nature if certain key essentials (such as peace and
stability) are removed from the upbringing of children's lives.
