Why didn't NASA send astronauts into space instead of spending millions on the pathfinder mission?

As a general rule, it's much cheaper to send robots into space than than people. So, the question should really be, "why would you ever send people". Of course there are some good reasons for that too; but since any scientific data (for example) that we want to obtain can usually be obtained cheaper with automated missions, that's what is usually done.

Why didn't NASA send astronauts to Mars instead of the unmanned 'Pathfinder' discovery mission?
Sending human beings to Mars is substantially more dangerous and expensive than sending an unmanned shuttle. It would take many days for astronauts to reach the red planet, and large quantities of supplies would need to be sent with them for them to survive the journey and to spend enough time on Mars to collect useful data and samples.
