'Now I need to do something about Uncle and Aunt when the war starts.' For Ren, as long as he had control of Uncle and Aunt, there were plenty of ways of using them.
'Though I hope I won't be forced into a situation in which I have to use them as tools to win this war.' Not only was he unwilling to go so far as to use the two people who had raised him as if he were their own child as tools to win a war, but the very thought of doing so made him deeply uncomfortable.
Not to mention, whether he admitted it to anyone or not, the fact that he was unworthy to sit on the Throne or even wear the Crown weighed heavily on his mind all the time. Now, if he couldn't even win a war against an exiled Crown Prince and had to resort to cheap tricks, such as using Aditya's parents, to secure his victory, then he would never feel content even if he won the war and remained the Emperor for the next 100,000 years.
