Wait people didn't see Falcon with guns in the previous movies
I did comment on Falcon killing people but mostly because it is a Disney property and having so many clear deaths was surprising(plus I was a little surprised that more people didn't complain but I guess that is happening now) BUT Falcon has guns, Falcon was an actual solider the killing people wasn't something strange for him unless we are pretending he is shooting rubber bullets at people.
They literally took away his guns for this show so when he transition to Captain America people won't say anything, They are going to pretend he wasn't dude running around with twin uzi in the other movies.
