Not all Christians are at the same maturity level. Some may struggle with doing certain things because they are associated with their old sinful lifestyle.
If the mature Christian is to be loving, they will not practice the actions (even though it is perfectly fine for them) out of love for their weaker brother or sister in Christ.
Be careful, however, that the exercise of your rights does not become a stumbling block to the weak. For if someone with a weak conscience sees you, with all your knowledge, eating in an idol’s temple, won’t that person be emboldened to eat what is sacrificed to idols? So this weak brother or sister, for whom Christ died, is destroyed by your knowledge. When you sin against them in this way and wound their weak conscience, you sin against Christ. Therefore, if what I eat causes my brother or sister to fall into sin, I will never eat meat again, so that I will not cause them to fall.
1 Corinthians 8:9-13
