You might have a child who seems to be 'just rotten to the core' and you feel like saying 'to hell with him/her...and just giving up on them and 'cutting them loose'....but WOULD YOU if you knew that a powerful negative entity that you CANNOT see is controlling your child? I doubt it ...as a loving parent you would try to get that child the spiritual help they need to be free again......going to a doctor and being prescribed chemical concoctions because they 'think' it might be this or that....will not solve this kind of problem...it will only damage the body of the child and create new additional problems...or just medicate (aka 'dope') them into a state of tranquility so your life gets easier having to cope with them....but they still will not be cured.
Again....just saying everything is not always 'as it seems'.....and you should never assume that someone only suffers because they 'did something bad and therefore deserve it'....sometimes it IS their own Karma that brings pain and suffering on them...but just as often it is precisely because the person is a light worker that they are persecuted by the darkness - because the darkness sees them as a threat.....if they were like the average 'Joe Public blissfully unaware of anything he cannot see' - who never does anything to confront evil (and usually hides from even facing it's existence) - they are left alone as a non-threat. Others make themselves susceptible by their own actions & thoughts, others by not adequately protecting themselves from the dangers arrayed against them....reciting a prayer every night makes no difference if you live a corrupt life...do you take the Creator for a fool that you can trick? Creator is forgiving yes...but 'foolish' no! Be sincere.
The wicked can fool themselves that they have achieved some kind of victory over your body when they cause you harm, but they have already been conquered by your immortal soul which they cannot touch. Some get knocked down into the mud and filth with swine sooner - so they can soar with Eagles above the storm clouds later.
