Opinions?

Let me apologize is advanced for the spam posting today, but I have a bit of a moral dilemma. I know I’ve talked about my biological father, but I don’t know if I’ve ever really mentioned that he has two other children that have no idea I exist. I have two brothers, who I’ve know about basically their entire lives, who I’ve never met, who I think I’d like to meet, and one of who is now 18 and has graduated high school. I’ve been tossing around the idea of reaching out to him. I haven’t done anything yet because I don’t know if I should. Is it fair to me to reach out to him? Is it fair to him for me to seek out this relationship that he doesn’t know exists? Is it selfish of me to do so? Because I know that it might flip his world upside down. What would I even say to him? How would I even begin? I don’t want to reach out with any hate in my words about his parents even though I do hate them with every ounce of me, but that’s not on him and it’s not his hate to take on. I don’t want my experiences to change how he views his family or himself. I don’t want to reach out for the wrong reasons. I don’t want reaching out to be an act of war on his family. I know nothing about him, but I think I’d like to. I don’t want him to hate me and I don’t want him to hate his parents. I want to be able to reach out with love and kindness, but how in the fuck do I do that? I want to extend an invitation for us to get to know each other as siblings, but is that selfish? I am stuck.
