Loving your neighbor as your yourself does not imply that you ought not kill your neighbor to prevent them from deliberately and intentionally acting in a manner that grievously violates your basic rights and dignity.

Further, Christian love, of the type regarded in the commandment, "Thou shalt love...", cannot be seen as emotive. It is a position in which we place ourselves with regard to others, taking into consideration their perspective. Christian love can easily be understood as equality of respect (in fact, this is what the vast majority of Christian theologians and philosophers have claimed for the past 2,000 years).

But, there is nothing inherently disrespectful in killing the person who, without justification, attempts to kill me, rape me, torture me, etc. If you believe that God is love and that he does condemn some souls to either hell or incredibly tortorous stints in pergatory, then you must believe that you can love someone while imposing physical pain and even death.
