[mcu] is what the avengers do at the beginning of age of ultron murder?

im having this debate with someone and to me it is. they didnt have to kill most of them, especially they didnt have to do it while joking, and showing no remorse afterwards. 

sure most of them dont have problems with killing but my point is that they kill them even when they didnt have to. they knew the base capabilities and could have stealth their way in or used the iron legion to dispose of the most of the goons in non lethal ways or used night night guns but didnt. it was literally a massacre.

Hydra is classified as a terorrist organization. It has aided or personally caused millions of deaths and is a major enemy of government organizations, and the people they killed were wielding illegal alien weaponry. Avengers is a vigilante organization granted general policing powers by governments and SHIELD. As such, legally, their deaths count as killing, not murder.

In terms of why they did this, HYDRA is a terrorist organization that has aided in or has killed millions of people. They have no reason to pussy foot around as that may let their higher ups escape with weapons that could kill millions more people. 

And we saw that was what the higher ups were trying to do.
