My wife was sexually assaulted a month ago and she finally told me today

Edit, people, please understand this is venting. Would I actually hurt a child, no, just beyond angry that there doesn't seem to be a way to truly make this man regret his actions. As for the rest of the advice given in the comments it's all greatly appreciated, I hoping tomorrow her and I can talk more about how we can work together to move forward and over come this part of our lives

Edit 2, since I forgot to put this in here, our children are only 3 years old and 4 months old, so I'm praying there isn't to much lasty damage but will certainly address the need for our oldest to get help with my wife when she's ready to talk about it more

Edit 3, talked to her more today and found out more about it, the guy had cornered her in the kitchen and forcefully pulled her pants down and did attempt to rape her. Makes me sick typing this.

My Wife today told me a month ago she went to visit a friend, upon arriving said friend wasnt home, but her husband was, he told my wife her friend would be back soon, so my wife waited there, The son of a bitch attempted to rape my wife with my fucking kids in the same room…and she was to scared to tell me because when the same thing happened to her in her previous marriage, her ex husband accused her of cheating….back to the present my blood is boiling, my wife made me swear not to go after the sick fuck, but god knows I could do it, I could so easily track him down and take a baseball bat to the POS knees, cripple him for life, smash his hands into nothing…..I even went as far as to call a close friend and ask them to provide an alibi…this friend was the first person to come to mind as soon as I began planning all of this, knowing for years they've always said they'd have my back no matter what…they suddenly became my voice of reason, telling me to think of my wife and kids, how they need me and I can't just throw it away for one scum bag….God knows I want to be there for them, I'll carry the world on my back, I'll let life kick me while I'm down over and over if it means they're happy, but I can never forgive those who rape others, be it women, children or even male victims, no one deserves to feel like they can't shower or bathe themselves enough to wash away how violated they feel….when I say I'm perfectly content with going each sex offenders door and ridding the world of them, I fucking mean it…To see the life slowly leave their eyes after countless hours of torturing them would still allow me to sleep peacefully at night….this world is so fucked…people fucking suck, and there will never be a fitting sentence to punish these fucking monsters….I just wish I could make her nightmares stop….I wish I could make this demon suffer the way my wife is…..and as I sit here crying, writing this, I was sworn to never tell another soul…only her therapist and I know what has happened…it's eating me up inside because I now have this unyielding hatred for a single person…..a part of me wants to become the very monster he'll fear, I want to torment his family, take away their feeling of being safe, have his kids cry and beg him to tell them why this mean man is tormenting their every waking moment, make him explain to them all the disgusting things he's done to his victims. Make him atone and beg for forgiveness, force him to watch as his family is systematically executed before his very eyes, making sure their screams are so embedded into his thoughts that every single second he draws breath he hears their screams replaying in his head endlessly tormenting him and even all of this doesn't feel like it's enough to make him suffer for what he's done to my wife….for the rest of my life now I have to sit here knowing a part of my wife has been taken away from her and I'll never be able to make her feel whole again, I've failed her, the one thing I've always told her I'd move mountains to protect her, to keep the demons at bay and to shield her from the corruption that has ruined this world...on that note....there is some fireball with my name on it.
