Apparently, killing people doesn't suffice in ISIS' eyes, which is why the extremists have now turned their "loving attention" to Palmyra's ancient history. To most Westerners, destroying an ancient amphitheater doesn't make sense. Sadly it does to ISIS. The amphitheater is, in ISIS' mind, a relic of Syria's non-Islamic past. That part of history has to be destroyed so Syria can be 100 percent Islamic.
