A Demon Friendly Culture

In Luke 8 Y'shua casts a legion of demons into a heard of pigs. Why did He not cast them into the abyss? What does that mean for us as we navigate a world where there are still demon about? What is it about our current culture that is so demon friendly? Clearly, dealing with demons was a big part of Y'shua's ministry and when He sent his disciples out, he gave them authority over demons.
