Sorry, but it appears you are quite wrong.
From the article:
“She was indefatigable. She just kept going,” he said Tuesday. “She was not someone who would take naps in the afternoon, or not show up for any function, dinner or anything else. She was always there, fully present. She kept going, always.”
I knew a guy who was a very outspoken but peaceful vegan, didn't want to harm anything. Animal rights activist. Super nice guy, when sober.
But he also had a drinking problem, and totally flipped when he drank, you could almost see the switch happen in a few seconds when he was at 4-5 beers. His drunk personality was angry, paranoid, quarreling and violent, and he would often get blackout drunk and get into fights and whatnot. Got himself banned from several bars.
I didn't know him well, but he probably had some trauma/bad shit in his life. He never talked about his family, except his grandmother who apparently had raised him, more or less.
