Next episode best case scenario: Garrett go fully psycho (because he is TAHITIed but they do not know the side effects - maybe Raina know).

Or just Garrett needed to know the reaction of Ward for his order.
Maybe it didn't matter what Ward would do, Garrett just needed to know what would he do.
He looked for an loyal agent to train (and lamented SHIELD was not loyal to him as him was to SHIELD) and not for a psychopats ready to stab him in the back when…

The point is not about Ward killing Garrett, but Ward killing his attachment to Garrett.
Attachment is weakness and Ward attachment to Garrett is a weakness.

If I remember, sometimes he had pants on

This is what "special force" trainees do.
They need people able to kill even if they are attached to the victim.

"These are not the aircrafts you are looking for"

"He was going to, but then Ward agreed that they should both eat Bambi instead." corrected.

It has not stealth capabilities.
Only helicarriers have it.

"He is adopted!!!" (cit.)

This would explain something:
1) The Clairvoyant talk with Coulson was in the presence of Ward and Garrett
2) Zola say he can foresee the behaviour of people looking at their records. This is the reason he could not "read" Coulson (he was a broken man not knowing he was broken). TAHITI made him unforeseable
3) The same…

He is not, because, he surely had to be X-rayed sometimes, after some missions, just to check he has no broken bone or internal bleeding.

Probably, by rules, they avoid to kill policemen in public when possible.

What part of "resuscitation" do you not understand?
Coulson's TAHITI experimented on dead people.
You can not kill dead.

Shang-Chi would be awesome, if they bring in his father: Fu-Manchu

And now we know WHY her face was burned and WHO did it.

Lola is a flying car. Not a land speeder.
She fly like an airplane and can hoover like an helicopter.

They were SHIELD.
They are government agents and they can legally initiate the use of (lethal) force if you oppose them.
If you do not like what they do, call a lawyers and find a judge.

"if Coulson's crew were hardened rogue soldiers/covert operatives. "
No, they are "family".

Neighbours were not happy with her rehearsals at home, so she does them at the theather, when no one is there.

The team could not handle Batroc if they caught him sleeping, naked, on a rock. He is way over their pay level.
Maybe, if they had Deathlock on their side, they could manage to just get beaten and not humiliated.
