We are the only responsible for what we are doing or not, which means that generating "negative" or "positive" karma is not an exception. They can do whatever they want, but they can not control our "
free will", which is the key for generating karma for ourselves.
Manipulating others is a thing, but what does manipulation means? -
Making someone to act, think or feel in a certain way, as you wish.
You can not
force it, but you can approach in different ways to deceive, convience them one way or another, and how the the target will react, feel and think is all up on their
free will. This free will makes the karma work, and the seal is always
their decision, there will be no one who can be 'more' responsible for what they do, and no one can make decisions instead of them neither. Others can not create your karma, it is rather sound like an excuse for me, which closes out responsibility above your own existence -
and I'm very stern about that -.
Getting manipulated is NOT an excuse for doing karmically "negative" things neither.
So I am not certainly agree with "
in anyways they choose" in this way (might be because of how I experience and see the things, it does not mean that I am right), but I clearly confirm and agree that many demons are exceptional masters of manipulating, and this can make them dangerous especially for those who are naive, having lack of intelligence and lower their guard.
As for their destructive effect on lives and reincarnations: As I stated above in my recent post, they are easily can follow down your soul's path in reincarnations for many reasons, and they can choose to do it for malicious reasons. So no doubt, they can ruin your reincarnations and they usually have the advantage, because they can set up the stage and plant everything they need to put their effect on you and lead you down on a path they planned for you.
If they "freshly" popping up in your life, they still can have the reason to destroy it, which can even reach the point where your life falls in grave danger and trust me, they can pretty much affect the material world, more than you have imagine.
Several demon has proved to being a part of my previous lives and we know each other way longer than before my soul decided to "come down". I didn't feel "fight" between Infernals and Celestials in a way like you,
@Amur , but I can definitely feel the tension between the two times to times when both of them around.
