tbh ive realized this thought can be counterproductive and really just feels like more reassurance to me personally at least   i realized at some point that doing erp meant not countering intrusive thoughts with this mantra and then invariably ruminating for hours about whether it was even true like the other commenter points out it might not be and is definitely a lot more nuanced in reality but instead accepting that maybe i am a bad person maybe bad people do worry about being bad people i can never know for sure and just have to live with that i have to sit with uncertainty  at the end of the day it boils down to this this phrase tries to give certainty and trying to gain certainty and assuage doubt is reassurance  on the other hand i think this phrase is helpful for people whove just learned they might have ocd and for understanding the difference between intrusive thoughts and actually being a murderer or whatever but i think it can very easily become a compulsion
