California-based Intercom CEO Eoghan McCabe, whose company is a heavyweight in the artificial intelligence customer service space, faced backlash Wednesday after urging for the public execution of a man accused of stabbing a Ukrainian refugee on a North Carolina train.

“I do think that rapid, public executions for crimes like this are a spiritual goal that we should point ourselves to,” McCabe wrote in a post featuring a screenshot of the scene. “I worry about Western society if we can’t react in proportion to how evil this is.”
