EU have its own agenda. They only wanted the syrians refugees (and some libyan refugees) for their need of cheap labor not all refugees. EU even had Operation Sophia to rescue migrants for their aging population. Once they got what they needed, they stoppped the operation.

It was never about "good moral" nor "right thing to do". It's by interest.

So now, whoever try to get into the mediteranean sea, will have to face the consequences. Whatever they make it or not.
