"算你厉害,算你狠"用英语怎么说?

alexcwlin comments:
I have to give it to you. You are (viciousand ruthless/a mean son-of-a-b****).”

Notes:
(1) “I have to give it to you” 是道地英文常见的词语, 意思是”我要承认你能够做到这些出人意表的事情”。
(2) “厉害”可以是好的厉害或是坏的厉害。
“vicious” 是凶恶的意思, 好的厉害可以用 incredible, or remarkable;
(3) “ruthless” 是“辣手无情” 的意思。
(4) “mean” 是“卑鄙”
(5) 用”sob” 时要小心，很容易得罪人。
