The self-harm is an extension of the aggression when your aggressive emotion starts to attack your own. If you would like to avoid attacking others, it is one of the option to take unconsciously. The stress of the aggression is not meant to cause the self-mutilation originally, though it might be ended up with the social conflict if your stress is just released to others.
When the emotion is transferred to a self-harm, your stress is released to feel calm and comfortable again. It also means you should keep hurting yourself until you reach the fulfillment sufficiently to lower the stress level. However, the human brain is featured to require more actions to lower the next stress, which is eventually escalated to a more dangerous harm on yourself. If you cannot control its escalation, you should accidently commit a suicide as an extension of the self-harm.
The aggression is a primitive emotion, which is originally meant to attack others, not yourself. When your brain is more controlled by the primitive feeling, your bare aggression makes you fight with others. It implies the self-harm is a result of the function of the frontal lobe and cerebral cortex, where the reason contains an emotion to be exploded.
When your emotion is exploded, your frontal lobe cannot function to stop you, while cerebellum is fully in charge of your action. The reason is not functional at this time, which makes you hard to remember the causality and circumstance. You just have a memory of the instantaneous image and feeling, which is also a proof that your frontal lobe is out of the function. Conversely saying, you can control your aggressive behavior when your frontal lobe is still intact.
You might attack others, even if you can still contain your emotion. Your irregular action is justified by the social reasoning, such as the brutal action during the war. Although, this is somehow out of the human nature, hence some of them have severely suffered from PTSD.
There is another irregular case to attack others with a rational mind, when you are lack of the empathy. It might be a disorder of the mirror neuron or the oxytocin and your reason has no capacity to stop a transformation from the aggression to the attack. This is a result of the brain deficit which some of the psychopath suffer from.
In both cases, the attack is justified by the total brain reasoning. It does not matter where the justification comes from, but it is necessary to be justified by your brain to initiate the brutal action. The brain can process many inputs emotionally or rationally, to output the behavior to take.
The issue is how deeply the electromagnetic wave can control the brain. The aggression is apparently raised by the radiowave irradiation. It increases a stress which should be released somehow, as you cannot keep it in your brain for long. It should be exploded in some forms, but the same frequency pattern cannot control a direction where the stress advances.
That means the manipulator cannot control its behavioral direction just by enhancing the aggressive emotion, rather it depends on your nature. If you are the person to contain yourself to attack others originally, your aggression won’t be released to others. It is more like you are going to hurt yourself when the stress of aggression is boosted to the extreme level.
However, if you have a clear target of its aggression, there is a possibility that you would attack this person. It is quite natural to feel stressed against someone when living a normal life. When you are electromagnetically controlled at this time moment to increase the aggression, its emotion should have a clear object, eventually to attack this person.
Even in this circumstance, you might contain yourself, which is totally depending on your nature. On the other hand, if you are accustomed to attacking others, your frontal lobe cannot restrain you from the brutal action when the radiowave is irradiated to boost the aggression. It is immediately transferred to the action to release the stress and it should be stopped when the stress is sufficiently lowered. Also in this case, there is an issue of the escalation that the stress can be reduced by the minor attack originally, though eventually ended up with the manslaughter.
All in all, the electromagnetic wave can increase the aggression, but the same frequency pattern cannot control the direction, which is more dependent on your nature. If the manipulator targets the real action in the end, it is required to manipulate with other ways as well. These mixed control eventually pushes you to commit a murder or a suicide.
