Why do “dead” people [and animals], or “sick” people [like a Zav or Metzora] make a person Tamei? What’s wrong with being dead or sick?

At the very least, we can suggest this is a message about what a human should strive for: םֶהָבּ יַחָו ! םיִיַּחַבּ ָתְּרַחָבוּ ! Chose life! So many of us have a subconscious love for hurting ourselves and “pitying” ourselves.
A person has to love life and enjoy Hashem’s beautiful world, especially the Nifla'os HaBo’rei. A person’s own greatness should be appreciated, not played down or ignored. We aim for health, happiness, and life. םיִקיִדַצ םיִיַח ןיִיוּרְק ןָתָתיִמְבּ וּליִפַא A Tzaddik is considered “ALIVE”, even after his passing.
