No …just serious things contrary to the Commandments etc…
This would seem to be the scruples

such can make it seem like that!
Look…things like these are grave matters:
Murder
Adultery
Masterbation
Abortion
lying under oath
stealing a large amount of money etc
being drunk (loosing ones reason)
Enslaving people
sacrificing to idols
sorcery
Burning down someones house
Missing Sunday Mass (unless sick etc)
lust
pornography
IVF
Contraception
Rejecting Christ
Things like that
As Christians though…we are set free from sin…and can walk by the Spirit …following Christ…yes we must say no to sin…but our focus needs to be on following Christ…living in thanksgiving as Paul urges…to the Father through Jesus Christ…
If we are in Christ…we are a new creation!
Do not net scruples drag you down…get a good confessor…and then keep “walking” with your focus on virtue…goodness…love…faith…hope…joy…on Christ…
Slowly you can move away from your scrupulosity…and know more and more the freedom of the Children of God…yes you can know then what really is sin…and especially mortal sin…and avoid it like you would avoid terrorists…or something…but with your eyes more and more on Christ and virtue…less on fear…more on hope and rejoicing in the truth…
Live in God!
