Albeit Jose's answer sounds more thematic
according to the rules, the DoW happens before:
● Diet Of Worms Rule. If the destination card contains a Bishop (of any color), both Bishops are killed in an exchange.
● Pacification Rule. Otherwise
, if the destination card moved to contains any Repressed Tokens, you
may choose one to Kill. There is no cost.21
At least that's my interpretation for that "otherwise".
