The Logic of Benevolent Aliens

I often hear people say horrible things about aliens, like they're gonna come and harvest our planet for resources, or enslave us, or wipe us out of existence. That just seems like projection to me.
I actually believe that it's inevitable that any species that has achieved interstellar travel has also embraced benevolent behavior. Here is my basic logic: To achieve interstellar travel, a species must harness powerful forces of physics. Without maturity and peacefulness, a species that has harnessed such powerful forces of nature would most likely destroy themselves.
By forces of nature, I'm specifically referring to the ability to create gravity. Gravity seems to be essential to interstellar travel for several reasons. First it is a means of propulsion that has the potential to transcend time and space. Secondly, physical bodies like ours are full of liquid sacs, like our eyeballs, and without proper gravity, planet-born creatures don't last very long.
Being able to generate gravity also means that a species has the ability to easily destroy not just their planet, but their whole solar system. Atomic power is pretty intense, but it is kinda wimpy compared to gravity. 
So far, we haven't blowing ourselves up with atomic bombs. It might be because we have some help from some benevolent aliens. Recently, Haim Eshed, former head of Israel's space program for nearly 30 years, said that extraterrestrials from The Galactic Federation have intervened several times to stop nuclear Armageddon.
Isn't that nice of them?
Humanity, in my opinion, is just now reaching the maturity level of a young adult. Teenagers often self-destruct. But adults tend to have enough experience to use some wisdom.

To a beautiful future!
