It may be induced by some bitter experience of past or it may be also an outcome of past anger. This grudge sometimes makes you feel that you have complete command over yourself and there is no other to take away from you. In some cases, it is a rational to hold grudges but everything can not be judged by rationality. Benevolence is something for which the earth still exists.

We can not let it go because it makes sense to us.
You should not hold grudge for long time because people are meant to make mistakes. At point of life, you should be kind and feel compassionate. Life teaches the same lesson. If you stuck with the grudge, it may bring a halt to certain part so your life. And the person whom you are grudged at may have changed themselves. So there is no point to uphold the ill feelings.
