Do you think I should tell my family the truth about the jabs?

Before c-19 I warned them nkt to get these jabs, but they went behind my back and got them... came back and mockingly told me they got their jabs, but even after warning them they're getting them sneakily. Now their hiding their health from me an illness their having.. a part of me wants to tell them they don't have much time left, but when I warn people they ignore and call me crazy. Most of my friends and family members won't listen and I'm afraid it may cause a rift.
