Security Blanket

i have always wondered..
can our instinct really be trusted? Do our morals really please others, ourselves or both parties? following your instinct can pose risks on outside situations, yet at the same time give you the security blanket of a good doing. while ignoring them or being untruthful can also prevent unnecessary debate but at the same time leave your morality feeling unjust, uncensored and uncleansed.
It can be difficult to tell at times whether to do as what your instincts tell you and let the truth risk trust but feel moral
or
leave the issue and feel guilty.
depends on the situation.
