Elvis gave millions to his loved ones, friends, charities, and total strangers...publicly and privately.

Elvis, at the height of his fame, was drafted into the US Army and rejected (as 99.9% of every other celebrity did) being a "military entertainer". Elvis went through all of the trials, training, and tribulations of every other member of the US Army and received an honorable discharge.
Elvis supported countless friends, and relatives, over a period of decades.

Elvis respected all Religions and was an avid reader of spiritual/religious books.
Elvis always acknowledged that God had blessed him and questioned "why" God chose him.
Elvis is the most successful Gospel recording artist, and received 3 Grammy Awards, in history.

Elvis was human and thus, and for the reasons listed herein, worthy of admiration.
Great question.
