It (violence) is increasingly frowned upon.
It is true for our small local universe (and again!) But it is not general.
Violence has become less exposed, less claimed, but little has really changed; in a recent article in Le Monde, referring to the military action in Mali, mention is made of the "cleaning" of a sector, a modest and hygienic term to designate the scattering of the intestines of Islamic terrorists (former "freedom fighters" in Libya).
See the authorities' care to show only "soft" images of the conflict.
In addition to traditional violence, often hidden and which tends to relocate (it too!), Was added an impersonal economic violence which became omnipresent.
It seems to me that you are making a regrettable confusion: certainly, a gain of wisdom would be desirable and would constitute a favorable change.
This is illustrated by the famous quote from Diogenes who was looking with his lantern, in broad daylight, for a "man"!
However this change towards more wisdom can only be the fact of oneself and moreover it is not (and cannot be, by definition) not at all the object and the finality of transhumanism.
