Sunday School lesson: Apostles and Daesh

Ok I just had this idea for a Sunday School lesson: the apostles of Jesus.

I'd like to focus on the book of Acts, St Paul and speak about the persecution of the apostles.

Maybe I could mention that the persecution of Christians hasn't stopped and I could even mention Daesh. Is this too controversial for Sunday School?

I know there's a board game based on the apostles and it seems interesting: it's called Commissioned. Has anyone tried it? Is there a Portuguese version?
Ok I've decided to abandon this subject, it's a terrible idea and they are too young to be talking about Daesh and religious violence.
