Information is important to humans because without information, no task can be performed. Therefore, information and communication technology (ICT) was invented and implemented to serve the needs of people. This facility has both positive and negative impacts on Thai society. However, it is generally the information technology ethics of the user that determines the direction of use of the technology. This chapter presents the relations among Thai culture, ICT, and IT ethics, in which all impacts are considered and described. The discussion in this chapter indicates that there are various factors related to development of IT ethics, but the one main factor is family background. Thus, in order to increase the IT ethics of users in an ICT world, the proposed solution in this chapter is to create a strong family and instruct children in their religion. Although this method is long-term, the outcome is worth the wait.
