Reconsideration
Reflection, Regret
noun, verbal noun
If you're anti conserve, I'm going to ask you to do some heavy reconsideration and reflection, and see if that's really the right way to be. If you change your thinking, you might even end up showing regret.
The reading for 反 is all good. The reading for 省 is an on'yomi reading you haven't seen yet. Here's a mnemonic to help you:
I'm standing in front of you, forcing a reconsideration of your anti conserve stance, with my saber (せい) to your throat. I better see some reflection on your face or you won't have one in a second.
反省しているので、そんなにきつく当たらないでください。
I’ve been reflecting on it, so please don’t be so hard on me.

My younger brother reconsidered it even more than I did.
コウイチ大統領とビエト副大統領は反省会を開いた。
