No regrets?

I'm working on this screenplay and one of the situations involved got me to thinking. Which I guess is a Good Thing.

One plot line involves the central character deciding to help another character--who is going to die in the next couple of days--to do something he's wanted to do for years. He'd never met his father--the father had left his mother while she was still pregnant with him. He knew who he is, knows where he is, but had never worked up the nerve to go and say hello to him. The kicker is, the character has no idea he's dying. That's sort of the point.

Anyway, the central character researches this and decides that it may be best to let the guy die without ever meeting his father. I won't go into details but she has a very good reason for this and it'll be obvious to anyone who sees the film. If it gets made. The character decides that it's not always a bad thing to have some unfulfilled desires, unmet goals, plain and simple regrets, when the end comes. She has ample experience with this, which again is sort of the point of the whole thing, but she does run into some controversy over it with other characters.

While it's not always a good idea to associate the morality and ethics of a character with those of the writer, I happen to agree with her. I think regret is a necessary component to a well-lived life--that someone who has no regrets really has no heart.

But maybe I'm wroing. What do you think?
