B. Positive and Indirect Suicide
 
Positive but indirect suicide committed without Divine 
consent is also unlawful unless, everything considered, there is sufficient reason for doing what will cause death to follow. Thus, it is not a 
sin, but an act of exalted 
virtue, to go into savage lands to preach the Gospel, or to the bedside of the plague stricken, to 
minister to them, although they who do so have before them the prospect of inevitable and speedy death; nor is it a 
sin for workmen in the discharge of 
duties to climb on roofs and buildings, thus exposing themselves to danger of death, etc. All this is lawful precisely because the act itself is good and upright, for in theory the 
persons in question have not in view either as end or means the 
evil result, that is, death, that will follow, and, moreover, if there be an 
evil result it is largely 
compensated for by the good and useful result which they seek. On the other hand there is 
sin in exposing oneself to danger of death to display 
courage, to win a wager, etc., because in all these cases the end does not in any way 
compensate for the danger of death that is run. To judge whether or not there is sufficient reason for an act which will apparently be followed by death, all the circumstances must be weighed, namely, the importance of the good result, the greater or less 
certainty of its being attained, the greater or less danger of death, etc., all questions which may in a specific case be very difficult to solve.
