After a disturbing video of a bullied bus monitor went viral, the bully victim has now received not only an apology from the bullies, but has also received over $500,000 in donations.

Caught on video, four middle-school kids verbally harassed 68-year-old Karen Klein to the point when she started crying. The video went viral online, gaining huge support from the public and an equally huge backlash against the bullies who have been receiving death threats.

Klein, ever the pacifist, has asked that no criminal charges be brought on to the boys. She also issued a plea to the public.

“I feel kinda bad for them and their families because of what’s going on,” she said. “They’re being harassed terribly, and I don’t like that. I don’t want any harm to come to them.”

The boys have since issued a public apology to Karen. “I feel really bad about what I did,” one of the boy tells CNN. “I wish I had never done those things. If that had happened to someone in my family, like my mother or grandmother, I would be really mad at the people who did that to them.”

“When I saw the video I was disgusted and could not believe I did that,” another has said. “I am sorry for being so mean, and I will never treat anyone this way again.”

An online donation for Klein has now reached over $500,000, and the amount is quickly growing.  “Maybe we can send her on a great, early retirement,” explained Max Sidorov who started the fund.

As for Klein, she is simply overwhelmed by everyone’s support. “I want to thank everybody for so much kindness,” she said.
