Because they wrote hi to be a psycho masquerading as a Good Guy.

I understand now the reason Providence:
to bring in people and see who can be trusted and who can not be trusted.

We could have a 24 season about Jack Bauer fighting some Hydra plot.
Would enjoy the kneecapping questioning of Hydra agents.

Funny the "you never was on top" line of May.

Blackbolt and Medusa are not blood dripping monsters.

Even in the last few years

Not blond enough?
Not shaved legs?

IIRC, because of the Secret Invasion, Hydra needed to destroy a few of its secret bases with a lot of people, when Strucker, like Fury, detected infiltrations.

Too many to care.
But this was before the chip brain implant and the soul thing.

Disgusted.
And the writers would not find a job anywhere.

The dog always run to retrieve the prey after it hear the shoot.
Ward shoot in the air, the dog run to retrieve the prey (even a quarter of mile away). Ward do not need to look at the dog and doing so would betray him with Garrett.
Garrett, with the scope, saw the dog running away.
Garrett know Ward soft spot. But also…

The details point to the Inhumans:
Attilan (the city of Inhumans) was, for some time, located in Tibet.
before it was on a North Atlantic Island and after it was on the Moon's Blue zone (before being blown up over New York).

IIRC, Killian was looking for funds when he met Stark the first time in the flashbacks.
Years later, we knew he obtained the funds from some other sources.
We also know the Extremis formula was available to Centipede (AKA Hydra).
AIM in the comics was a branch of Hydra (R&D) until it become autonomous.

She could be an Eternal or a Deviant.
The monster parents would side for Deviant.
Also Eternals rarely have children.
if the Celestials are looking for Skye, I think it would be obvious: they are just too large to miss. The smaller Celestial is probably 50 m high (and Exitar is 2 km high) and they are essentially…

Skrull are for FF4, so no.
Kree could be.
Inhuman is more probable.
But a frost giant or some other nordic lore could not be excluded.
They already hinted at other dimensions, so maybe Skye parents are from some other dimension (making her Dr. Strange stuff).
She could be Dormammu niece.

In fact, we do not why he tryed to kill his brother, burn down the house and so on.
Maybe he didn't did it at all.
We know he left military school, stole a car and drove to go home (why?)
What did his brother do? Why should he burn the house (or why brother or parents would burn the house)?

Lasers lose power with the square of the distance traveled.
1) The laser at the distance had low power and needed time to burn the curtain
2) The laser is so powerful it just ashed an hole in the curtain and the curtain started to burn just for reflected heat from the wall (not probable)

Rand, Metrobank (www.metrobankonline.co.uk) linked to deathlock comics in the past

The dog, like Skye and others, are friends he is attached to.
He can easily kill some unknown agent, some he just talk to, some random policeman or thugs, but his soft spot is he do not want kill friends.

Raina will be, IMO, the next big-bad, as we discover her past and her goals.
Even Garrett and Ward worry about her eyes and what is behind them.
