...and she was so friendly to him, and apologizing for the lateness in getting him out of there (because everyone was afraid of his powers and ready to kill him as shown in the trial later).

And Eren, in his madness and despair, was so brute and rude to them in last time they saw each other - and with bars between them again...

Eren's last interaction with Hange (Chapter 107):

So an interesting thing I noticed when comparing these is that in both scenes, Eren is behind bars. Their first interaction is mostly casual. Here, Eren has been locked away after being discovered to have the ability to turn into a titan. The people around him are scared and not sure what to do with him, but Hange is just hopeful and fascinated. "Maybe I shouldn't say this...but all we can do is believe in you."

Fast forward four years later. Eren has been locked up again, and this time it's for going out on his own and forcing his friends to go after him, endangering their lives and ending the life of one of them. He carries a much different demeanor than the boy that Hange first met. He is cold, stone-faced and angry. Despite efforts to understand him, she still cannot get to him and only manages to anger him even more. This is the last time they ever speak to each other, and now Hange has departed as well, ranting to Erwin and the others about Eren's wild antics. It's quite the shift from where they started, and I'll be interested to see how he reacts if he finds out whose death he caused this time. "You pervert! Ever the rebellious teen, huh?! Grow up, Eren!"

To beat up kid

OR

To let innocent blood be shed

And it's all to “prove their loyalty” to the cruel system

(2/2) And dud anyone noticed the way he glanced at her after that, when she was upset to death ? I thought his face could have said “see, brat ? I just saved your life, so be grateful”. 

Hey! Geez, I’ve never thought of it this way. Let’s see the trial in Levi’s perspective. There’s humanity’s last hope in front of him - the kind of weapon Erwin desperately wants in the Survey Corps. The boy looks innocent, but is being treated like a monster. 

All is fine until someone in the audience reveals his and Mikasa’s shared bloody past. They were forced to kill when they were children.

“The question is should we really trust him with our most talented people, our funds and the destiny of all the human kind?”

The answer is right there, in the same panel - Levi standing beside Erwin as his right-hand man. Erwin trusted someone like Levi, who we later learned was also a killer since such a young age, with the destiny of humankind. And he became humanity’s greatest soldier.

So why wouldn’t Erwin and Levi give a chance to Eren and Mikasa, knowing their potential, when Levi was given that chance?

Levi’s way to save them both was drastic (beating Eren up badly) but that was the only way he knew. He was raised in the midst of violence, but Eren and Mikasa’s situation relate to his, as we know now (much later in the manga). 

So yes, I believe Levi’s actions (and possible angry reaction) meant to save both Eren and Mikasa from the unfair trial. And Levi’s look at her could mean exactly that, “Why so angry? I just saved your and the brat’s life, so be grateful. We’re going to give you a chance, like Erwin once gave me despite our shitty past”
