Help a Friend convert

Assalamu Alaikum I have an important question and really need your help, especially from reverts! I have a friend that wants to convert. there are just two things that are a blockade for him. One thing are the war verses and the parts that sound for people that are not familiar with the Quran like we want to "kill unbelievers". I want to explain to him that it’s often taken out of the context. One thing that’s also stopping him are the things that happen in Muslim countries and immigrants in European countries do. He connects these people to Islam and also asked me why these people do all these things if Islam is such a peaceful religion, which I always tell him. But I didn’t really had an answer. Do you have any recommendations what I can tell him or any videos or websites where things like that are explained? The second thing is his family, which is pretty conservative Swiss. They are all atheist and Religion in general is just like a joke for them. This is really scary for him. His father is also a police officer so if they have to do with immigrants it’s mostly just negative which affected their general perspective and immigrants as well as Muslims. He’s really scared that they will not accept him if he converts. I really don’t know what to do… Barakallahu feekum!
