I think piccolo would be a good God of destruction because he understands the responsibilities of the gods and the supreme kais I think he would be able to make the difficult decisions of destroying planets without hesitation he doesn't have any family of his own he doesn't have anything else holding him back unless you want to say Gohan is his family but I think Gohan would understand if piccolo wanted to take the position but also I think it would be a unique take to see a namekian as a God of destruction
