Why would someone want to sell call options?
You appear to be thinking of option writers as if they were individuals with small, nondiversified, holdings and a particular view on what the underlying is going to do.  This is not the best way to think about them. Option writers are typically large institutions with large portfolios and that provide services in all sorts of different areas. At the same time as they are writing calls on a particular stock, they are writing puts on it and options on other stocks.  They are buying and selling the underlying and all kinds of different derivatives.  They are not necessarily writing the option because they are expecting or hoping to benefit from a price move.  It's just small part of their business.  They write the option if the option price is good enough that they think they are selling it for very slightly more than it's worth.   Asking why an option writer creates a call is like asking why a grocery store keeps buying groceries from their distributors.  Don't they know the price of food may not always rise?  Sure, but their business is selling the food for slightly more than they pay for it, not speculating on what will happen to its price.  Most option writers are doing the same thing, except what they are buying and selling is sets of cash flows and risk.   As a general rule, the business model of option writers is to profit from the few cents of spread or mispricing, not from aggregate changes in the price of the underlying.  They should and often do maintain balanced portfolios so their option writing activities don't expose them to a lot of risk. Also note that there could be lots of reasons for writing options, even if you do have a particular view.  For example, perhaps the option writer thinks volatility of the underlying will decrease.  Writing a call could be part of an overall strategy that profits from this view.
