Robin Williams, who passed away earlier this week, touched millions of people in a legendary career that often reminded us how wonderful a person can be.
Now, in a reminder of how terrible people can be, his grieving daughter Zelda Williams says she's quitting social media after being besieged by Internet trolls.
While countless fans have taken to the Internet to express their love and respect for Williams, many others sent horrific comments and pictures to Zelda.
The second-oldest of Robin Williams' children, Zelda initially took the fight to the trolls, asking supporters to report them to social media administrators.
Soon enough, realizing how fruitless this is, she decided it was better for her to delete her accounts, after posting a farewell apology and message:
"I'm sorry. I should've risen above," Williams Tweeted. "Deleting this from my devices for a good long time, maybe forever. Time will tell. Goodbye."
The mourning 25-year-old also suspended her Instagram, writing:
"I will be leaving this account for a bit while I heal and decide if I'll be deleting it or not. In this difficult time, please try to be respectful of the accounts of myself, my family and my friends."
Zelda defended herself for not sharing more photos of her dad - a ridiculous thing people harassed her about - as well as their relationship in general:
"Mining our accounts for photos of dad, or judging me on the number of them is cruel and unnecessary," she added, in response to online criticism.
"There are a couple throughout, but the real private moments I shared with him were precious, quiet, and believe it or not, not full of photos or 'selfies.'"
"I shared him with a world where everyone was taking their photo with him, but I was lucky enough to spend time with him without cameras too."
"That was more than enough, and I'm grateful for what little time I had. My favorite family photos are framed in my house, not posted on social media."
"They'll remain there. They would've wound up on the news or blogs then, and certainly would now. That's not what I want for our memories together."
"Thank you for your respect and understanding in this difficult time. Goodbye. Xo"
Zelda and her half-brothers Zak, 31, and Cody, 22, Robin's children from his previous marriages, continue to grieve along with his widow, Susan Schneider.
