Could you forgive your child's murderer

Idk why but I watched a video of a mother forgiving her daughter's murderer. The murderer did his jail time and said he regretted it, but personally, I would never be able to forgive the murderer.

However, when I asked my friends and some other people, I actually got mixed responses. Some said that forgiving is better because you can let go of your grudge and get a weight off your shoulders, while others strongly denied even considering forgiveness.

what do you guys think?
