His character's love story with Drucilla Winters (played by Victoria Rowell) became a favorite among fans of the show.
In real life, St. John dealt with drama that could have rivaled a soap opera.

St. John said during a 2014 interview with CBS that his family had been Hindu and his stepmother discovered the guru.
"Coming out of the '60s and '70s you had people who were really yearning and searching for God," he said. "My parents got caught up in it and I did too."
In 2014, St. John's 24-year-old son Julian died while a patient La Casa Psychiatric Health Facility in Long Beach, California.
The actor and his ex-wife, Mia, later filed suit against the facility.
St. John told "Entertainment Tonight" in 2017 that he was "angry" about the final footage the facility captured on video of his son.
"I watched it the first time, I'll never watch it again," he said. "It's not something I want to see."
He was open about his battles with depression following the death of his son and in 2017, Entertainment Weekly reported that the star had taken a leave of absence from his show to deal with mental health issues.
St. John's last activity on Twitter was January 21 when he retweeted a post which read, "Grieving the loss of a child is a process. It begins on the day your child passes, and ends the day the parent joins them."
He was set to marry his model girlfriend, Kseniya Mikhaleva.
