Sensitive Content 6+

Hi my 9 year old child is playing minecraft, and we discovered l that there are multiple skins with horror or violent intention, like axe in the head etc. It would be really great, if there were a possibility to switch this content off. There are also mini games like murder and mystery etc. where it would be great, when the title could be something with a less violent word. His little brother is a lot around and it evolves a big topic to him, that "there is a murder" and "killing" etc. and we all would have a better time, when we could add a filter in language and content. Thank you!
