I similarly do not want to check it out myself because I do not want to view said content. That being said, some posts on the subreddit states that the version of Sad Satan on itch.io does have CP and gore. I hope a moderator can check it out and address the problem accordingly.
Viewing post in Sad Satan
Sad Satan is effectively an internet urban legend. You’re going to have people spreading rumors about what it is, and others reusing the name their own projects to try to capitalize on the scary & unknown factor.
At this time there is nothing to suggest this page should be removed, and if others are telling you otherwise then they are likely just trolling you.
There’s even a Wikipedia page on Sad Satan:
https://en.wikipedia.org/wiki/Sad_Satan
Initially, some followers were skeptical of the game, fearing it may contain gore or child pornography. However, the owner of Obscure Horror Corner shared that, so far in his playthroughs, the game had not contained any such material.
Hope that helps
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...
Also, your using of the Wikipedia article directly states:
Minutes before the update, a new version of the game was posted to 4chan by someone claiming to be ZK, claiming that Obscure Horror Corner had not been showing their viewers the "true" Sad Satan. Members of the 4chan community downloaded this version of the game and attempted to play it. Some users complained that their computers began running sluggishly, and a few even reported that their computers became completely unresponsive while trying to run the game. A few users even reported that their computers would not turn on anymore after running this version of the game. One Reddit user attempted to play the game from a Live USBinstead of from his computer's main hard drive. Later, when this user tried to boot up his computer, the computer failed to start up normally. This version of the game, dubbed the "clone" by most of the /r/sadsatan community, contained images of violent gore and child pornography, some of which were accessible right from the title screen; resulting in another version of the game with this graphic material removed (which is often called the "clean" version) being created by Redditors and subsequently redistributed.
