There is no such thing as "society", just relationships between individual people. To get a better "society", you need people to act better. However, all of recorded history suggests that people are pretty universally willing to use other people as tools to benefit themselves. (Obviously not everyone does this all the time or to the same amount.) History also makes it clear that passing laws will not work: despite laws against things that are evenly timelessly non-virtuous, like stealing and murder, do not prevent murder and theft. In fact in Judeo-Christian thinking, to do this requires people receiving a "new heart, a heart of flesh instead of a heart of stone" from God. (I saw "Judeo-" because the passages is from Ezekiel, which is common to both. I do not know if rabbinical thinking agrees, however.) Even if it does not require a divine gift, certainly the problem has proven intractable up to the present time.
"determine who should be removed from society" is just a scary thought. Who gets to determine that? How can we be sure they are right? What prevents them from using this as a tool to eliminate people that are competitors or whom they simply dislike? In fact, this has a name: "to purge". The Soviet Union under Stalin and the Chinese Cultural Revolution were scary times.
