THE DIALOGUE REEL
既然这是你的选择
“Since this is your choice,”
本王便 成全你
“I shall grant it.”
我错了
“I was wrong.”
“If you insist on courting death, I will gladly destroy you right now.”
While '成全' normally denotes benevolence in helping lovers unite or fulfilling dreams, in martial or court dramas it frequently takes on a dark, threatening meaning: 'granting' someone the demise they recklessly chose.
