The answer to this question depends on the position the society takes in this scenario. If the society is within the story in which the archetypes appear then the scapegoat archetype would likely be seen as the most evil by a large part of society, seeing as it is described as being "seen as the embodiment of evil and is shunned by society." It would therefore be logical to assume that the person who embodies this archetype would also be seen as the embodiment of evil and be shunned by society. 
If the question is interpreted as society judging the archetypes by themselves, rather than someone who is embodying the architype, then the trickster archetype would likely be seen as particularly evil. Characters that embody this archetype such as the Marvel character Loki have been portrayed as the antagonist in many fictional stories. The scapegoat archetype is generally only seen as evil if the observer is not aware that the individual embodying that archetype, is in fact embodying that archetype. 

It has to be noted however, that general assessments may not be shared by individuals within a society or be shared by all societies.
