Sports Fans: Why in the world would anyone settle for a draw?

I’m referring to soccer (futbol). I totally hate the fact that games can end in a draw. What are the pros and cons? How do draws pan out in a positive or negative manner towards a team? Can someone please explain to me how they respect a draw in a soccer match? Also, how does it help out the playoff system in soccer. I’m really trying to get into soccer and understand it. The rest of the world stands behind it, I’m just trying to understand how it all works.
