Sometimes we tend to push some people a little bit too much, and in the process they are forced to be in a lose-lose situation… this is when you should cease your actions no matter what the reason is…

Desperate times call for desperate measures - Unknown

Since a person is pushed to his limits, he will do what he can to bring you down if you push him further. It is a scary thought because a man with nothing more to lose have available last-resorts. Before you push him again, make sure you are willing or capable of losing as much as he would because if you are not, then it will end with the both of you down and beaten… But with you on the disadvatage because he already had nothing to lose halfway down and you are still to lose half of yourself.

Look for signs.

Two of the last aspects a person would lose before the point of desperation are pride and dignity respectively. Once he gives up on there, you better hide or be ready for a sudden death. Driving one person to such extents terminates his rationality and re-activates primal instincts and he will fixate on inflicting maximum damage for his impending loss.

A beast is most dangerous when it is cornered.

That person may be trying to flee from you to begin with. Drive him to a corner and he would have no other choice but to fight. To this effect, he will see any single bit of damage done to you as a worthy cause. Look at the Iraqi insurgents, they have lost their homeland to a foreign invader, branded as terrorists, and lost their way of lives. They developed the thinking that every life of an Iraqi for an American is well worth it. What’s worse is that it is indubitably true. Americans have easy lives, while an Iraqi is most likely within the range of suffering. The former probably earns in a month whatever the Iraqis earn in a year, so basing it on lifestyle, good trade.

I am not sure what recourse should one take, but I know that one should not drive another past their limits.
