“Boston. F**king horrible:” this is how actor Patton Oswalt began his Facebook post about the Boston Marathon Explosion on Monday.

Oswalt brought up 9/11 and how he had “had it with humanity,” but eventually turned his concentration towards all of the brave people who run into the destruction instead of away from it.

“You watch the videos of the carnage and there are people running TOWARDS the destruction to help out,” he said. “… The vast majority stand against that darkness and, like white blood cells attacking a virus, they dilute and weaken and eventually wash away the evil doers and, more importantly, the damage they wreak.”

Oswalt's reaction to the tragedy was shared nearly 90,000 times on Facebook and had more than 100,000 likes.

While the “Young Adult” star needed more than 140 characters to speak his mind, celebrities like Donnie Wahlberg, Mandy Moore, Maria Menounos and Tom Bergeron took to Twitter sharing their sentiments and prayers.

New Kids on the Block member Joey McIntyre, who was running in the marathon, missed the explosision by a few minutes, he said.

“There was an explosion by the finish line about 5 minutes after I finished- I'm ok but I'm sure there are many hurt.”

His bandmates, Donnie Wahlberg and Jordan Knight, tweeted to let their fans know McIntyre wasn’t injured in the tragedy.

“Just heard that @joeymcintyre is ok! Thanks to everyone for tweeting! Scared for everyone else in Boston.#PrayerForBoston please,” Wahlberg wrote.

The following is a slew of tweets by celebrites who voiced their concerend about the Boston Marathon tragedy:

Such a senseless and tragic day. My family and I send our love to our beloved and resilient Boston.
