Assuming your question is "Is person's ego a projection of the responses of their amygdala onto the conscious experience?", I think it would translate to "Does the amygdala determines or houses the ego". In that light, the question hinges on the meaning of ego. Given the question is asked at Cognitive Sciences SE, I assume the ego is "The part of the mind that mediates between the conscious and the unconscious and is responsible for reality testing and a sense of personal identity". In that case I would say no, the amygdala is not involved in the ego.
Generally, the amygdala is considered to be an essential part of the limbic system. The limbic system indeed controls the core emotions (fear, pleasure, anger) and drives behaviors essential to life (hunger, sex, and the care of offspring). The functions of the amygdala are indeed mainly associated with emotions, but also with learning and memory (Martin & Hans, 1985). A notable example is post-traumatic stress disorder (Shin et al., 2006), where it mediates imprinting of memories through fear.
However, the amygdala definitely shapes "the self". Given the Latin meaning of "ego" (literally, "I") one could definitely argue for an essential role of the amygdala in the ego. In that context, though, arguably every single part of the brain at the macroscopic level is an essential part of the ego.
