Let me put my point of view on this.I have been watching this thread for long but was not getting right thing to say
For makar lagna mars is the worse malefic even though it is in lagna and exhalted .
What we for got to see here is that aspetc of mars and saturn is on 7th house and aspect os malefic has to be considerd
in sync to its natural nature.
Also being functional malefic for makar lagan this will instead aggravate mangal dosha and since placed with saturn it will
further elevate the effect.
I will continue later.
