Fun fact, both Enron and Lehman Brothers were in the S&P 500 when they went bankrupt. So yes, the whole market or even the market of the largest companies, includes some that may not be great companies. The beauty of the index is you don't have to know or care, since it'll take care of itself over time.

Yes. That’s what passive investing is. You give money to the passive fund, the passive fund buys the market. No regard to price or any other metric.
