yes, you still care about the cash flow. Paying more to principle is not very smart, esp. these day. The money got stuck in the property until you sell the property. Having more cash mean more security, esp. during recession time.

Once you put money into the property, it would be very hard for you to get it out, esp. in rental property in hard times. If one day you are having some financial hardship, you might have some trouble to feed the negative cash flow. Then you might be forced to sell, which means you might lose far more money for having to sell in the very wrong time.
