“You don’t know me, but you tried to kill me,” Marjory Stoneman Douglas High School teacher Stacy Lippel said to Nikolas Cruz in court.

“I will have a scar on my arm and the memory of you pointing your gun at me engrained in my brain forever. The person I was at 2:20 on Wednesday, Feb. 14, 2018, is not the same one who stands here today. I am broken and altered and I will never look at the world the same way again,” Lippel said. “A part of me is damaged and I can feel how different I am.”

She said she struggles with trust, is always thinking about the worst-case scenario, and is left with guilt, wishing she could have done more to save her colleagues and students. She said her husband’s and children’s innocence were stripped away, too.

Lippel said she’s “disgusted” that Cruz was spared the death penalty.

“My hope for you is that you die sooner rather than later,” calling him a “monster.”

After Lippel’s statement, Judge Elizabeth Scherer called her a “hero.”

Terri Rabinovitz, grandmother of 14-year-old victim Alyssa Alhadeff, said Florida’s Supreme Court should reexamine the law that requires a jury’s decision be unanimous for the death penalty.

“I’m too old to see you live out your life sentence, but I hope your every breathing moment here on earth is miserable and you repent for your sins, Nikolas, and burn in hell,” she said.

Florida Gov. Ron DeSantis has called on the state legislature to change the death sentencing rules in the wake of the Cruz verdict.

Debbie Hixon, wife of Chris Hixon, a 49-year-old coach killed in the school shooting, addressed Nikolas Cruz directly on Tuesday morning.

She said her husband “was stolen from us by an unimaginable act that you planned and executed.”

“You did not receive the justice that you deserve,” she said. “You were given a gift -- a gift of grace and mercy. Something you did not show to any of your victims. I wish nothing for you today. After today I don’t care what happens to you … you’ll be a number.”

“Today we close this chapter,” Hixon continued. She said she’ll choose to remember all of the positive memories of her husband, instead of the “darkness.”

Chris Hixon’s son, Thomas Hixon, said to Cruz, "You're not a disturbed or broken person," but instead "lacks character."

By killing his father, Thomas Hixon said Cruz "weakened a family, a community and generations of young adults by taking their strongest advocate out of their corner."

He called Cruz "living proof that evil does exist in our world."

Hours after the sentence was announced on Oct. 13, Manuel Oliver, whose 17-year-old son, Joaquin, was among the victims, told ABC News Live he had hoped for the death penalty.

"Even the death penalty was not enough for me," he said. "The way that Joaquin died ... the amount of suffering and pain, the shooter will have never received that punishment."

His wife, Patricia Oliver, told ABC News she feels enraged by the jury’s decision, and said her son did not get justice.

To jurors who voted against the death penalty, she said, "They have to live with that in their conscience. Life is about karma. They will remember what they did when the time comes."

Fred Guttenberg, whose 14-year-old daughter, Jaime, was killed in the massacre, said he was “stunned” by the verdict.

"I could not be more disappointed," he told reporters on Oct. 13. "I don't know how this jury came to the conclusions that they did."

"This decision today only makes it more likely that the next mass shooting will be attempted," he said.

Guttenberg said he thinks the next mass shooter is planning his attack now, and "that person now believes that they can get away with it."

"There are 17 victims that did not receive justice today,” Guttenberg said. "This jury failed our families today. But I will tell you: The monster is gonna go to prison, and in prison, I hope and pray, he receives the kind of mercy from prisoners that he showed to my daughter and the 16 others. … He will die in prison, and I will be waiting to read that news on that."

The father of 35-year-old Scott Beigel, a geography teacher and cross-country coach at Marjory Stoneman Douglas High School, said the "system failed."

"The fact that I have to share my world with you is disgusting," he said, addressing Cruz during his statement. "The fact that I have to breathe the same air you breathe is reprehensible."

He called Cruz a coward, among several expletives, and said he hopes for "prison justice."

"I have to learn to live with the pain that you caused to my entire family," he said. "You are the lowest form of pond scum, and I apologize to pond scum for equating you with them."

He said his son was kind, had character and cared for his fellow human beings -- "something you never did," he said to Cruz.

His wife, Linda Schulman, recalled how her son managed to save 31 students during the shooting.

She read the names of the 17 victims killed in the shooting, including her "irreplaceable son."

"These are the innocent lives that we will remember and celebrate forever," she said.
