I can relate. For me it's my father.
When I was little he warned me that suicides end up in hell. Children who fail to 'Honour thy Father' would also end up in hell. Every moment he had with me was spent proselytizing his religious beliefs, and gaslighting me into thinking I'm obliged to reciprocate his providing for me. Every now and then he would jog my memory, reminding me of the happy moments we spent together, and insist that he has been a 'good and responsible father'. He has no reservations using emotional blackmail, and weaponizing his religion to keep us hostage.
