ISIS 'Executions'.

Why are the media referring to 'ISIS Executions'? These quasi human vermin cannot execute anyone as their only legitimacy is in their own eyes. An 'execution' suggests the culmination of due legal process. These people are murderers - nothing less. As a believer, do I want to see them obliterated? - Certainly. But it would still be my preference for them to find The Living Lord as their Saviour from the hell which is their certain fate as things currently stand. Please pray - even for them!
