wouldn't it be Great if saying Sorry actually helped people ?

That is a sweet thought. Yes it would.

Wouldn't it be great if people didn't randomly capitalize words in the middle of a sentence for no reason?

Maybe if it's said with sincerity, but can I honestly say that it fixes things. No. One needs to accept that said sorry before it can help.

If it is sincere it might help the other person to forgive and get past things.
