I recently joined a mostly neutral, mid-level campaign. The trouble is that one of the characters decided that his character was going insane, and made himself an insanity die roller (randomly by the way, nothing happened in game to justify this happening). Upon returning to the capital city, he killed two civilians and a few guards after being caught. Between another character's assistance and low rolls, I didn't catch on to what he did to intervene. Those I could live with, some people are just murder-hobos, and that was a very RP heavy session. Then, as we were leaving the city to progress the campaign, he sneaked away from the party, and did some really bad things that I won't go into detail about.
Several other players voiced their complaints. Since he's related to the DM, the DM said he will not do anything about it as long as his rolls are successful (he has the Lucky feat, and gets inspiration for complimenting DM) so they almost always are. I openly told him that if my character ever sees him do anything, EVER, that I'll kill his character.
As it stands, I see myself with several options, none of which are great.
Cast "Ceremony -Atonement" and hope I get lucky with the DC 20 insight check to attempt to fix his alignment, without any proficiency or wisdom bonuses to help.
Kill his character, and potentially endure his and DM's hatred
Ask DM if I can make a new character, but then lose all my gear, money, weapons, ETC.
Leave the game and try to find a new game to join (which I won't be able to, as no one else in my area hosts DnD/pathfinder/TTRPG games)
My question:
Is there anything I can do in this situation to not lose out on this group without alienating both offending player and DM? Would it be better to just give up on the group and hope I find an alternative? Any advice would be greatly appreciated, as none of my current options are great...
