Sure, it's not going to be easy; there will be a bit more crime and a bit more poverty. But there are a few points to consider. First, the number of refugees would amount to no more a few percent of the local European population. It's not a "demographic shock". Second, the entire Middle East was under European control or various degrees of meddling for a very long time (hell, the entire world), and nobody asked them when Europe came barging in. With power comes responsibility, you reap what you sow etc. etc.. Finally, if compassion didn't have a price, it wouldn't be worth much.
