The law allows lethal force in self defense if you have a reasonable fear of serious bodily harm, not necessarily strictly in fear for your life. If you're being attacked by people who have had a pattern of abuse and violent bullying, this level of force could be justified. I do think there is merit to a self defense claim.
The simulacrum is never that which conceals the truth, it is the truth which conceals that there is none. The simulacrum is true. Ecclesiastes
