Please Consider The Beginners, And Don't Be So Selfish plz

I was just playing in a bots game as in the midland, and I was there because I was informed that in order to better myself, I should probably go to either a bots game or a custom game and practice cs'ing. All was going well and dandy, but then i started noticing two of my human teammates begin to continuously get double kills and kill the bots with ease (not gonna name any manes here *cough cough . I have no problem with people doing really well in bot matches, as playing against the bots isn't a difficult task. So I then I proceeded to ask them why they were in this match, playing against these bots, because they were clearly good enough to be playing against other real people. The one and the only reason I was asking here is because we had a very new on our team who was being pushed from lane to lane because these two were too focused on getting kills rather than letting actual new players get the experience they need playing against bots. One of them answered that they needed 1 ip. Then, they got super butthurt and asked me what rank i was. I told them i was Silver 4. Then I asked them. was Silver 5 and was Gold 5. Then they proceeded to tell me that I should suck a dck and that i should stfu. Guys, please don't be these people. Sorry this rant was too rant-y. I just want this to hopefully not be a thing in the future.
