I think it is fair to speculate that any alien race that has sufficiently advanced technology to cross the vast distances involved in interstellar travel, has technology massively more advanced then we mere earthlings possess.
I believe that it is also fair to speculate that any such aliens have passed successfully through the filter of internecine combat in order to develop such advanced technology whereas on our planet, such conflicts are, and seemingly always have been, commonplace and extremely destructive (see WWI, WWII and Ukraine for further details).
I suppose mankind should draw some comfort from the fact that some weapons of mass destruction; for example nerve gas and biological weapons, have been banned by international treaty even if some have been used fairly recently for example by Saddam Hussein and chemical Ali, in Iraq. I suppose it is also of some comfort that nuclear weapons have only been used in anger twice (Hiroshima and Nagasaki); their appalling destructive power having once been demonstrated, thankfully no country has found it acceptable to use them again; here I hope vehemently that I don't have to eat my words in the context of Ukraine.
In the light of the foregoing, I believe it is reasonable to speculate that an alien civilization that has developed the ability to travel interstellar distances, it is far more likely to be nurturing than extremely belligerent as the latter would most likely have destroyed their civilization before they reached the stage of developing interstellar travel.
