I did not want to directly link this: https://scareberezk.itch.io/sad-satan
But I heard this version has some questionable content. If I recall correctly from the subreddit r/sadsatan, I do not think there is CP or malware, but I think there is real gore (not sure about this).
Furthermore, the correct story of Sad Satan is that there are multiple versions of Sad Satan. First, an edited version of the game was released to the public that was generally safe (no real gore, no CP, no malware). But a person by the name of ZK claimed the originally released version was edited and gave a link to the true version (which had malware, gore and CP). There are numerous versions of the game out there, some completely safe, others not having malware or CP but real life gore, and some with CP, gore, and malware.
I highly recommend someone to check out the link above and see if its safe or not because I am not brave enough to do so myself...
