Jai shri ram 🙏🙏, depends what do you mean by character if you mean his loyalty of him with his spouse then check his 7th house if it is afflicted or not by planet like Mars, rahu. Check his venus if it is with Mars and rahu this will give the native tendency to be in illicit relationships. Now check if the lagna is also in effect of such planets like afflicted venus , rahu and Mars if the native might be involved in such acts but if lagna is not affected by these planets and comes in contact with guru or exalted 9th Lord the native will have control over himself and do right things. Remember only afflicted lagna does not mean lack of loyalty and only afflicted 7th house and venus do not mean lack of loyalty both the conditions should be satisfied.
