Jesus saved only a handful of people while he was on this earth, not the entire world. He was doing good in small isolated instances. He has not removed death and sickness for everyone. If he wanted to he would. He doesn't want to. And why should he?

Deu 28:22 (ESVST) 22 The Lord will strike you with wasting disease and with fever, inflammation and fiery heat, and with drought and with blight and with mildew.
Deu 28:27 (ESVST) 27 The Lord will strike you with the boils of Egypt, and with tumors and scabs and itch, of which you cannot be healed.
Deu 28:28 (ESVST) 28 The Lord will strike you with madness and blindness and confusion of mind,
Deu 28:35 (ESVST) 35 The Lord will strike you on the knees and on the legs with grievous boils of which you cannot be healed, from the sole of your foot to the crown of your head.

You're view is borderline blasphemy against God.
