Jesus did seem to mention false prophets and increasing wickedness in later days, and the love of many waning thin.
The Bible clearly teaches a time of great trouble called the last days. (2 Timothy 3:1-5) Jesus prophesied that during the time when he would take his power in heaven to rule as king, there would be a composite sign of his invisible presence, consisting of wars, food shortages, pestilence, earthquakes, and as you mentioned, increasing lawlessness and lack of love. (Matthew 24, Luke 21, Mark 13)
The evidence of these Bible prophesies being fulfilled in the 20th and now 21st centuries is abundant. We are living in the final part of the last days. Soon the prophecies concerning the end of this system will be fulfilled, when Christ takes over rulership of the earth, destroying all human governments, and bringing God's kingdom rule over the earth. (Revelation 19:11-21, 16:14-16, Daniel 2:44)
