得理不饒人英文

大家好！

I was recently watching a TV show and heard the following dialogue:

A:你说我怎么这么没有眼力见儿呢？ 我光看他开的是什么车我就应该知道他不是一般人啊。你说我找他麻烦干嘛呢？
B:没那么严重。你呀，就是得理不饶人

（Context: a girl (A) is talking about getting into a car accident with the 总代表 of (what I presume to be) a famous company)

Does anyone know what 得理不饶人 means?
（Does it mean "logical" but "unwilling to forgive"?)

Thanks!

得理 = 占理, 有理, 有道理 "be in the right"
不饒人 = 不讓人, 咄咄逼人 "be unforgiving, merciless, uncompromising, pushy, argumentative, relentlessly wanting to make another wrong, ruthlessly demanding as if seizing on and exploiting others' mistakes"
得理 + 不饒人 = "be in the right" + (and thus) + "be pushy and unforgiving"
If one is 得理不饒人, he is being pushy and unforgiving simply because he thinks he is in the right or has the upper hand in an argument.

Thanks for your excellent explanation, Skatinginbc!
