GOOD DEED OR BAD DEED

Once a hungry cat caught a rat. The rat requested to leave him but the cat was so hungry that there is no chance he will let that rat to escape.so he did not notice rat's request and started moving towards his home. In the way of his home they met a monk passing by to the nearest village for getting some food. When the rat saw the monk he anyhow escaped from that rat and ran towards the monk. He asked for monks help to save his life from that cat.
The rat already get injured by the cat so he requested the monk to help him. The monk understood the situation and asked the cat to forgive rat's life. But the cat told him that he was hungry for days and if he will not get his food then he might die soon.
By listening this the monk told both of them that saving life of others is his prime duty and he cannot let the cat to eat this rat. He assured the cat that he will collect some food from near by village, and also some medicine for that injured
rat , until that the cat had to promise him that he will not eat that rat nor he attack that rat again but will save him. Both cat and rat got agreed upon his suggestion.
That day the monk took little longer to collect some food from village nearby, And when he returned to that place he was shocked to see that both that cat and the rat had already died. The cat died because of hunger and the rat died because he was severely injured by the cat.

The monk did not understood that what he had done........

Was it a good deed or a bad deed?
