I don' know if you will find this of any help, but I have homicidal idealizations as well. I have since I was around 23. Since then i have not actually been diagnosed with schizophrenia or BPD but that is what my therapist have been looking towards. I am now in the process of getting into an actual psychiatrist so that i can finally be diagnosed. But since the homicidal thoughts started I have also had many voices in my head, hallucinate both visually and tactically, and also seem to lose reality sometimes. Suicidal thoughts happen a lot also. So it could be possible that it could be the Schizophrenia or a type of it since that is what they are thinking for me. But just remember that no two people are alike. A lot of mental illnesses like to mock each other making it hard to know exactly which one you may or may not have. But i do wish you the best. Like the others have said, just don't dwell on them to much. I have noticed when I do that my other symptoms tend to get worse as well and then i start to obsess over it all.
