what's the best thing did michael do?

The best thing that he did???
He did the best in everything!!!! everything he did was always the best!!
Behind the musician, the genius.. he was an angel, always an agel ready to help, to heal, to care, to love..
He gave so much 愛 to us and to the people that were so lucky to be around him..
"Heal the world" speaks so well about Michael..

愛 IS THE MESAGE♥♥♥

His charity work, money donations, everything he did for helping children and people in need.

It depends on what あなた understand under "best". The best thing Michael did is simply being Michael ;)
