According to Christian Science, can you attack people you don't know with Malicious Animal Magnetism? If not, how do they explain battle deaths?

Christian Scientists, if I understand them correctly, believe that most deaths are caused by Malicious Animal Magnetism. That's why Mary Baker Eddy, when she got a severe case of pneumonia in 1911 (which she ended up dying from), blamed that pneumonia not on a germ, but on Malicious Animal Magnetism done by people who are against her. That's also why, when her husband died, and doctors said he had a heart attack, she insisted he died of arsenic poisoning mentally delivered. However, quite a few deaths in the real world appear to be caused by other people, but not necessarily against the people who know you. Deaths in a battle, for example. The German soldier who killed William McBride in 1916 was presumably shooting around with a gun randomly, not targetting William McBride specifically. Or terrorist attacks, for example. So, do Christian Scientists believe that it is possible to attack a group of people with Malicious Animal Magnetism, without necessarily knowing anybody from that group of people?
