Thank you. Nice easy change too :)

The directive responsible for their unceremonious self-destruction is configured in the xml files. If you want to allow them to be downed and captured, it is certainly possible to go into the files and make a little edit to remove ABF_Directive_Synstruct_Martyr from the requiredDirectives on all of the appropriate pawn kinds. Having mod settings to tweak this would require me to have code editing Defs after the game has loaded, which is generally frowned upon in modding.

Any chance you could implement a mod option for it that they don't self destruct on defeat? Would love to capture some for some... Voluntold labour :P
