Heartbreaking

I wanted to say "I'm sorry" to the elderly eventho I'm not the one doing the wrong things....I felt so useless and seriously pity them... Their hope,hopes that time will change something and God will gives them back their son... I feel tired for them and I also feel heartbreaking for them... Look at how they grow older and older everytime I come back... Things and recent behavior makes me giving up on him... I do feel telling him or asking him " Why do you come back if you decided to run?" ..  Will this black sheep turns white? How many percent that can ensure one day he will regret what he is doing? When will he really learn to appreciate? When will he know the meaning of "responsible" ? Can I just hit him for once to wake him up? I don't mind putting a knife at his hand and call him to stab me if those stabbing can really change everything.. His every moves and behavior now is just like stabbing me time after time... Dear God,they don't deserved such things at this stage in life...
