Your opinions are just that, but not really nuanced.

1) This is a huge matter of character. If you cannot be faithful to your wife, what makes you a faithful leader of a company? There is also the issue of respect: when a leader is morally compromised, the people he is leading lose confidence and respect in him.

2) Isn’t there something of a power dynamic issue here too? He has a greater responsibility to use his authority and power as a superior to not abuse that authority, and committing adultery with an inferior is a huge problem.

3) On what basis is this a huge deal and the previous two are not? Where’s the nuance? It’s just arbitrary.

4) Well yeah, it looks like he was complicit in breaking sanctions. It’s no longer an arms-length deal.

5) Again, why are the first two worth shrugging shoulders and this one is not? It’s no big deal, people cheat and break the law all the time.

6) That sure undersells it. It underlines the stupidity of sin, and the sinfulness of man.

7) I can’t argue with that.
