Mark Taylor, otherwise known as the Kiwi Jihadi or Bumbling Jihadi, had an unhealthy addiction to video war games, one of his former wives said.
In an interview with Stuff in 2014, the Indonesian woman said the Islamic State militant would argue with her about the gaming addiction.
"I have problem with his unstable character and addicted to play war game. He played game every day in long hours [sic],' Stuff reports.
"He promised to change but finally he can't. We keep arguing every day about his bad habit and he was unhappy with me being hard on him about it."
Speaking to ABC yesterday, the former New Zealand soldier revealed he wanted to come back to New Zealand after surrendering to Kurdish forces.
