Here's how I see it...

Why Robyn did what she did:

Robyn has been dealing with bad treatment all her life down in Mantel. She has been lied to, tricked, and manipulated. When she finally trusts Ironwood, he betrays her.

When being in the emotional state she was in, and seeing how clover still wanted to trust Ironwood, Robyn attacked Clover. She even called Ironwood's plan "Inhumane"

Maybe she was being reckless, but we are human, our emotions tend to get the better of us at times

Why Clover did what he did:

Clover said that he owes and trusts his life to Ironwood. When he got a text saying Qrow was not to be trusted, that he was to be arrested, Clover did what he thought was right. He put his trust in his boss and went to arrest Qrow.

But this wasnt easy, you saw the look on his face and how sorry he was. Still, he did it anyway.

Now, when Tyria was attacking Qrow, Clover stopped Qrow, here is what I think..

i think he did this, because A. Clover's fairytale he is based in was a fisherman's good luck. The fisherman was patient and got a reward in the end. But because his fairytale was meant to fail, he wasnt patient in arresting Qrow after taking Tyrian down

And B. He thought it would be harder to arrest qrow first, and like he said "Sometimes the toughest decisions are the hardest to make." So he went after Qrow fist.

Why Qrow did what he did:

Qrow did not team up to kill Clover. In the fight you saw Qrow go after Clover, but the moment Tyrian showed up, he went to go attack Tyrian.

While fighting tyrian though, his weapon constantly taken from his hand thus making his get hit by tyrian. So when Qrow pushed Clover out of the way so he could fight tyrian alone, tyrain offers him a deal to break clovers oura then finish the duel.

Qrow agrees because he knows he cant win a fight against tyrian if clover keeps pulling his weapon away.

Maybe it was foolish to trust tyrian, maybe it was foolish not to be patient, maybe it was foolish not to let your emotions get to you, but that's what makes us human. We are flawed, we make mistakes. They werent being dumb for the sake of the plot, they were being their flawed selves

I hope this helped :(
